In the lead-up to her solo show, institutions of Resolution Disputes [iRD], at Transfer Gallery, Brooklyn, I caught up with Rosa Menkman over two gallons of home-brewed coffee. We talked about what the show might become, discussing a series of alternate resolutions and realities that exist parallel to our daily modes of perception. iRD is open to visitors on Saturdays at Transfer Gallery until April 18th, and will also function as host to my and Morehshin Allahyari’s 3D Additivist Manifesto, on Thursday April 16th. Rosa Menkman: The upcoming exhibition at Transfer is an illustration of my practice based PhD research on resolutions. It will be called ‘institutions of Resolution Disputes’, in short iRD and will be about the liminal, alternative modes of data or information representation, that are obfuscated by technological conventions. The title is a bit wonky as I wish for it to reflect that kind of ambiguity that invokes curiosity. In any case, I always feel that every person, at least once in their grown-up life, wants to start an institution. There are a few of those moments in life, like “Now I am tired of the school system, I want to start my own school!”; and “Now I am ready to become an architect!”, so this is my dream after wanting to become an architect. Daniel Rourke: To establish your own institution?

RM: First of all, I am multiplexing the term institution here. ‘institutions’ and the whole setting of iRD does mimic a (white box) institute, however the iRD does not just stand for a formal organization that you can just walk into. The institutions also revisit a slightly more compound framework that hails from late 1970s, formulated by Joseph Goguen and Rod Burstall, who dealt with the growing complexities at stake when connecting different logical systems (such as databases and programming languages) within computer sciences. A main result of these non-logical institutions is that different logical systems can be ‘glued’ together at the ‘substrata levels’, the illogical frameworks through which computation also takes place. Secondly, while the term ’resolution’ generally simply refers to a standard (measurement) embedded in the technological domain, I believe that a resolution indeed functions as a settlement (solution), but at the same time exists as a space of compromise between different actors (languages, objects, materialities) who dispute their stakes (frame rate, number of pixels and colors, etc.), following rules (protocols) within the ever growing digital territories. So to answer your question; maybe in a way the iRD is sort of an anti-protological institute or institute for anti-utopic, obfuscated or dysfunctional resolutions. DR: It makes me think of Donna Haraway’s Manifesto for Cyborgs, and especially a line that has been echoing around my head recently:

“No objects, spaces, or bodies are sacred in themselves; any component can be interfaced with any other if the proper standard, the proper code, can be constructed for processing signals in a common language.”

By using the terms ‘obfuscation’ and ‘dysfunction’ you are invoking a will – perhaps on your part, but also on the part of the resolutions themselves – to be recognised. I love that gesture. I can hear the objects in iRD speaking out; making themselves heard, perhaps for the first time. In The 3D Additivist Manifesto we set out to imagine what the existence of Haraway’s ‘common language’ might mean for the unrealised, “the powerless to be born.” Can I take it that your institute has a similar aim in mind? A place for the ‘otherwise’ to be empowered, or at least to be recognised?

RM: The iRD indeed kind of functions as a stage for non-protocological resolutions, or radical digital materialism. I always feel like I should say here, that generally, I am not against function or efficiency. These are good qualities, they make the world move forward. On the other hand, I do believe that there is a covert, nepotist cartel of protocols that governs the flows and resolutions of data and information just for the sake of functionality and efficiency. The sole aim of this cartel is to uphold the dogma of modern computation, which is about making actors function together (resonate) as efficiently as possible, tweaking out resources to maximum capacity, without bottlenecks, clicks, hicks or cuts, etc. But this dogma also obfuscates a compromise that we never question. And this is where my problem lies: efficiency and functionality are shaping our objects. Any of these actors could also operate under lower, worse or just different resolutions. Yet we have not been taught to see, think or question any of these resolutions. They are obfuscated and we are blind to them. I want to be able to at least entertain the option of round video (strip video from its interface!), to write inside non-quadrilateral, modular text editors (no more linear reading!) or to listen to (sonify) my rainbows (gradients). Right now, the protocols in place simply do not make this possible, or even worse, they have blocked these functionalities. There is this whole alternate universe of computational objects, ways that our data would look or be used like, if the protocols and their resolutions had been tweaked differently. The iRD reflects on this, and searches, if you will, a computation of many dimensions. DR: Meaning that a desktop document could have its corners folded back, and odd, non standard tessellations would be possible, with overlapping and intersecting work spaces?

RM: Yes! Exactly! Right now in the field of imagery, all compressions are quadrilateral, ecology dependent, standard solutions (compromises) following an equation in which data flows are plotted against actors that deal with the efficiency/functionality duality in storage, processing and transmission. I am interested in creating circles, pentagons and other more organic manifolds! If we would do this, the whole machine would work differently. We could create a modular and syphoning relationships between files, and just as in jon Satroms’ 2011 QTzrk installation, video would have multiple timelines and soundtracks, it could even contain some form of layer-space! DR: So the iRD is also a place for some of those alternate ‘solutions’ that are in dispute? RM: Absolutely. However, while I am not a programmer, I also don’t believe that imagining new resolutions means to absolve of all existing resolutions and their inherent artifacts. History and ecology play a big role in the construction of a resolution, which is why I will also host some of my favorite, classic solutions and their inherent (normally obfuscated) artifacts at the iRD, such as scan lines, DCT blocks, and JPEG2000 wavelets.

The iRD could easily function as a Wunderkammer for artifacts that already exist within our current resolutions. But to me this would be a needles move towards the style of the Evil Media Distribution Center, created by YoHa (Matsuko Yokokoji and Graham Harwood) for the 2013 Transmediale. I love to visit Curiosity Cabinets, but at the same time, these places are kind of dead, celebrating objects that are often shielded behind glass (or plastic). I can imagine the man responsible for such a collection. There he sits, in the corner, smoking a pipe, looking over his conquests. But this kind of collection does not activate anything! Its just ones own private boutique collection of evil! For a dispute to take place we need action! Objects need to have – or be given – a voice! DR: …and the alternate possible resolutions can be played out, can be realised, without solidifying them as symbols of something dead and forgotten. RM: Right! It would be easy and pretty to have those objects in a Wunderkammer type of display. Or as Readymades in a Boîte-en-valise but it just feels so sad. That would not be zombie like but dead-dead. A static capture of hopelessness. DR: The Wunderkammer had a resurgence a few years ago. Lots of artists used the form as a curatorial paradigm, allowing them to enact their practice as artist and curator. A response, perhaps, to the web, the internet, and the archive. Aggregated objects, documents and other forms placed together to create essayistic exhibitions. RM: I feel right now, this could be an easy way out. It would be a great way out, however, as I said, I feel the need to do something else, something more active. I will smoke that cigar some other day.

DR: So you wouldn’t want to consider the whole of Transfer Gallery as a Wunderkammer that you were working inside of? RM: It is one possibility. But it is not my favorite. I would rather make works against the established resolutions, works that are built to break out of a pre-existing mediatic flow. Works that were built to go beyond a specific conventional use. For example, I recently did this exhibition in The Netherlands where I got to install a really big wallpaper, which I think gained me a new, alternative perspectives on digital materiality. I glitched a JPEG and zoomed in on its DCT blocks and it was sooo beautiful, but also so scalable and pokable. It became an alternative level of real to me, somehow. DR: Does it tesselate and repeat, like conventional wallpaper? RM: It does repeat in places. I would do it completely differently if I did it again. Actually, for the iRD I am considering to zoom into the JPEG2000 wavelets. I thought it would be interesting to make a psychedelic installation like this. It’s like somebody vomited onto the wall.

DR: [laughs] It does look organic, like bacteria trying to organise. RM: Yeah. It really feels like something that has its own agency somehow.

DR: That’s the thing about JPEG2000 – and the only reason I know about that format, by the way, is because of your Vernacular of File Formats - the idea that they had to come up with a non-regular block shape for the image format that didn’t contradict with the artifacts in the bones and bodies that were being imaged. It feels more organic because of that. It doesn’t look like what you expect an image format to look like, it looks like what I expect life to look like, close up. RM: It looks like ‘Game of Life’. DR: Yes! Like Game of Life. And I assume that now they don’t need to use JPEG2000 because the imaging resolution is high enough on the machines to supersede bone artifacts. I love that. I love the effect caused when you’ve blown it up here. It looks wonderful. What is the original source for this? RM: I would blow this image [the one from A Vernacular of File Formats] up to hell. Blow it up until there is no pixel anymore. It shouldn’t be too cute. These structures are built to be bigger. Have you seen the Glitch Timond (2014)? The work itself is about glitches that have gained a folkloric meaning over time, these artifact now refer to hackers, ghosts or AI. They are hung in the shape of a diamond. The images themselves are not square, and I can install them on top of the wallpaper somehow, at different depths. Maybe I could expand on that piece, by putting broken shaped photos, and shadows flying around. It could be beautiful like that.

DR: It makes me think of the spatiality of the gallery. So that the audience would feel like they were inside a broken codec or something. Inside the actual coding mechanism of the image, rather than the standardised image at the point of its visual resolution. RM: Oh! And I want to have a smoke machine! There should be something that breaks up vision and then reveals something. DR: I like that as a metaphor for how the gallery functions as well. There are heaps of curatorial standards, like placing works at line of sight, or asking the audience to travel through the space in a particular order and mode of viewing. The gallery space itself is already limited and constructed through a huge, long history of standardisations, by external influences of fashion and tradition, and others enforced by the standards of the printing press, or the screen etc. So how do you make it so that when an audience walks into the gallery they feel as though they are not in a normal, euclidean space anymore? Like they have gone outside normal space? RM: That’s what I want! Disintegrate the architecture. But now I am like, “Yo guys, I want to dream, and I want it to be real in three weeks…” DR: “Hey guys, I want to break your reality!” [laughs] RM: One step is in place, Do you remember Ryan Maguire who is responsible for The Ghost in the MP3? His research is about MP3 compressions and basically what sounds are cut away by this compression algorithm, simply put: it puts shows what sounds the MP3 compression normally cuts out as irrelevant – in a way it inverses the compression and puts the ‘irrelevant’ or deleted data on display. I asked him to rework the soundtrack to ‘Beyond Resolution’, one of the two videowork of the iRD that is accompanied by my remix of professional grin by Knalpot and Ryan said yes! And so it was done! Super exciting.   DR: Yes. I thought that was a fantastic project. I love that as a proposition too… What would the equivalent of that form of ghosting be in terms of these alternate, disputed resolutions? What’s the remainder? I don’t understand technical formats as clearly as you do, so abstract things like ‘the ghost’, ‘the remainder’ are my way into understanding them. An abstract way in to a technical concept. So what is the metaphoric equivalent of that remainder in your work? For instance, I think it depends on what this was originally an image of. I think that is important. RM: The previous image of JPEG2000 does not deal with the question of lost information. I think what you are after is an inversed Alvin Lucier ‘Sitting in a Room’ experiment, one that only shows the “generation loss” (instead of the generation left over, which is what we usually get to see or hear in art projects). I think that would be a reasonable equivalent to Ryan Maguires MP3 compression work. Or maybe Supraconductivity. I can struggle with this for… for at least two more days. In any case I want the iRD to have a soundtrack. Actually, it would like there to be a spatial soundtrack; the ghost soundtrack in the room and the original available only on a wifi access point. DR: I’m really excited by that idea of ghostly presence and absence, you know. In terms of spatiality, scan lines, euclidean space… RM: It’s a whole bundle of things! [laughs] “Come on scan lines, come to the institutions, swim with the ghosts!” DR: It makes me think of cheesy things you get in a children’s museum. Those illusion rooms, that look normal through a little window, but when you go into them they are slanted in a certain way, so that a child can look bigger than an adult through the window frame. You know what I mean? They play with perspective in a really simple way, it’s all about the framing mechanism, the way the audience’s view has been controlled, regulated and perverted. RM: I was almost at a point where I was calling people in New York and asked, “Can you produce a huge stained glass window, in 2 weeks?” I think it would be beautiful if the Institute had its own window. I would take a photo of what you could see out of the real window, and then make the resolution of that photo really crappy, and create a real stained glass window, and install that in the gallery at its original place. If I have time one day I would love to do that, working with real craftspeople on that. I think that in the future the iRD might have a window through which we interface the outside. Every group of people that share the same ideas and perspectives on obfuscation need to have a secret handshake. So that is what I am actually working on right now. Ha, You didn’t see that coming? [Laughs] DR: [Laughs] No… that’s a different angle. RM: I want people to have a patch! A secret patch. You remember Trevor Paglen’s book on the symbology of military patches?

DR: Oh yeah. Where he tries to decode the military patches? Yes, I love that. RM: Yeah, I don’t think the world will ever have enough patches. They are such an icon for secret handshakes. I have been playing around with this DCT image. I want to use it as a key to the institutions, which basically are a manifest to the reasonings behind this whole exhibition, but then encrypted in a macroblock font (I embedded an image of Institution 1 earlier). There was one of Paglen’s patches that really stood out for me; the black on black one. The iRD patch should be inspired by that.

DR: Hito Steyerl’s work How Not to be Seen: A Fucking Didactic Educational .MOV File, centres on the grid used by the military to calibrate their satellites from space. The DCT structure looks a lot like that, but I know the DCT is not about calibration. It contains all the shapes necessary to compose any image? RM: If you look up close at a badly compressed JPEG, you will notice the image consist of macroblocks. A macroblock is a block organizations, usually consisting of 8×8 pixels, that posses color (chrominance) and light (luminance) values embedded via DCT (discrete cosine transform). Basically all JPEGs you have ever seen are build out of this finite set of 64 macroblocks. Considering that JPEGs make up the vast majority of images we encounter on a daily basis, I think it is pretty amazing how simple this part of the JPEG compression really is. But the patch should of course not just be square. Do you know the TV series Battlestar Galactica, where they have the corners cut off all their books? All the paper in that world follows this weird, octagonal shape? Or Borges Library and its crimson hexagon, that holds all knowledge. I love those randomly cryptic geometric forms… DR: It reminds me of a 1987 anime film, Wings of Honneamise, that had a really wonderfully designed world. Everything is different, from paper sizes and shapes, through to their cutlery. Really detailed design from the ground up, all the standards and traditions. RM: Like this Minecraft book too. The Blockpedia. DR: Oh that’s great. I love the Minecraft style and the mythos that has arisen around it. RM: So Minecraft and Borges follow a 6 corner resolution, and Battlestar paper has 8 corners… Discrepancy! I want to reference them all! DR: So these will go into the badges? RM: I want to have a black on black embroidered patch with corners. Don’t you think this would be so pretty? This black on black. I want to drop a reference to 1984, too, Orwell or Apple, the decoder can decide. These kind of secret, underground references, I like those. DR: A crypto exhibition. RM: It’s so hot right now (and with hot I do not mean cool). Since the 90s musicians encrypt or transcode things in their sounds, from Aphex Twin, to Goodiepal and now TCF, who allegedly encrypted an image from the police riots in Athens into one of his songs. However, he is a young Scandinavian musician so that makes me wonder if the crypto design in this case is confusingly non-political. Either way, I want to rebel against this apparent new found hotness of crypto-everything, which is why I made Tacit:Blue.

Tacit:Blue uses a very basic form of encryption. Its archaic, dumb and decommissioned. Every flash shows a next line of my ‘secret message’ encrypted in masonic pigpen. When it flickers it gives a little piece of the message which really is just me ranting about secrecy. So if someone is interested in my opinion, they can decode that.

Actually, the technology behind the video is much more interesting. Do you know The Nova Drone? Its a small AV synthesizer designed by Casper Electronics. The the flickr frequency of this military RGB LED on the top of the board can be altered by turning the RGB oscillators. When I come close to the LED with the lens of my iphone, the frequencies of the LED and the iphone camera do not sync up. What happens is a rolling shutter effect. The camera has to interpret the input and something is gone, lost in translation. In fact, a Resolutional Dispute takes place right there. DR: So the dispute happens because framerate of the camera conflicts with the flicker of the LED? RM: And the sound is the actual sound of the electronics. In Tacit:Blue I do not use the NovaDrone in a ‘clean’ way, I am actually misusing it (if there is such a thing when it comes to a device of dispute). Some of the sounds and disruptions of flow are created in this patch bay, which is where you can patch the LFOs, etc. Anyway, when you disconnect the patch it flickers, but I never take it out fully so it creates this classic, noisy electric effect. What do you think about the text? Do you think this works? I like this masonic pigpen, its a very simple, nostalgic old quiff. DR: It reminds me of the title sequence for Alien. Dave Addey did a close visual, sci-fi etymological, analysis of the typography in Alien. It went viral online recently. Did you see that?

RM: No! DR: It is fantastic. Everything from the title sequence to the buttons on the control panel in the background. Full of amazing insights.

RM: Wow, inspiring!

So with any cypher you also need a key, which is why I named the video Tacit:Blue, a reference to the old Northrop Tacit Blue stealth surveillance aircraft. The aircraft was used to develop techniques against passive radar detection, but has been decommissioned now, just like the masonic pigpen encryption. DR: This reminds me of Eyal Weizman. He has written a lot on the Israeli / Palestinian conflict as a spatial phenomena. So we don’t think about territory merely as a series of lines drawn on a globe anymore, but as a stack, including everything from airspace, all the way down beneath the ground, where waste, gas and water are distributed. The mode by which water is delivered underground often cuts across conflicted territories on the surface. A stacked vision of territory brings into question the very notion of a ‘conflict’ and a ‘resolution’. I recently saw him give a lecture on the Forensic Architecture project, which engages in disputes metered against US Military activities. Military drones are now so advanced that they can target a missile through the roof of a house, and have it plunge several floors before it explodes. It means that individual people can be targeted on a particular floor. The drone strike leaves a mark in the roof which is – and this is Weizman’s terminology - ‘beneath the threshold of detectability’. And that threshold also happens to be the size of a human body: about 1 metre square. Military satellites have a pixel size that effectively translates to 1 metre square at ground level. So to be invisible, or technically undetectable, a strike needs only to fall within a single pixel of a satellite imaging system. These drone strikes are designed to work beneath that threshold. In terms of what you are talking about in Trevor Paglen’s work, and the Northrop Tacit Blue, those technologies were designed to exist beneath, or parallel to, optic thresholds, but now those thresholds are not optic as much as they are about digital standards and resolution densities. So that shares the same space as the codecs and file formats you are interested in. Your patch seems to bring that together, the analogue pixel calibration that Steyerl refers to is also part of that history. So I wonder whether there are images that cannot possibly be resolved out of DCT blocks. You know what I mean? I think your work asks that question. What images, shapes, and objects exist that are not possible to construct out of this grid? What realities are outside of the threshold of these blocks to resolve? It may even be the case that we are not capable of imagining such things, because of course these blocks have been formed in conjunction with the human visual system. The image is always already a compromise between the human perceptual limit and a separately defined technical limit. RM: Yes, well I can imagine vector graphics, or mesh based graphics where the lines are not just a connection between two points, but also a value could be what you are after. But I am not sure. At some point I thought that people entering the iRD could pay a couple of dollars for one of these patches, but if they don’t put the money down, then they would be obliged to go into the exhibition wearing earplugs. DR: [Laughs] So they’d be allowed in, but they’d have one of their senses dampened? RM: Yes, wearing earmuffs, or weird glasses or something like that. [Laughs] DR: Glasses with really fine scan lines on them that conflict with TV images or whatever. RM: [Laughs] And I was thinking, well, there should be a divide between people. To realise that what you see is just one threshold that has been lifted to only a few. There are always thresholds, you know. DR: Ways to invite the audience into the spaces and thresholds that are beneath the zones of resolutional detectability? RM: Or maybe just to show the mechanics behind objects and thresholds. DR: Absolutely. So to go back to your Tacit:Blue video, in regards the font, I like the aesthetic, but I wonder whether you could play with that zone of detectability a little more. You could have the video display at a frequency that is hard for people to concentrate on, for instance, and then put the cryptographic message at a different frequency. Having zones that do not match up, so that different elements of the work cut through different disputed spaces. Much harder to detect. And more subliminal, because video adheres to other sets of standards and processes beyond scan lines, the conflict between those standards opens up another space of possibilities. It makes me think about Takeshi Murata’s Untitled (Pink Dot). I love that work because it uses datamoshing to question more about video codecs than just I and P frames. That’s what sets this work apart, for me, from other datamoshed works. He also plays with layers, and post production in the way the pink dot is realised. As it unfolds you see the pink dot as a layer behind the Rambo footage, and then it gets datamoshed into the footage, and then it is a layer in front of it, and then the datamosh tears into it and the dot become part of the Rambo miasma, and then the dot comes back as a surface again. So all the time he is playing with the layering of the piece, and the framing is not just about one moment to the next, but it also it exposes something about Murata’s super slick production process. He must have datamoshed parts of the video, and then post-produced the dot onto the surface of that, and then exported that and datamoshed that, and then fed it back into the studio again to add more layers. So it is not one video being datamoshed, but a practice unfolding, and the pink dot remains a kind of standard that runs through the whole piece, resonating in the soundtrack, and pushing to all elements of the image. The work is spatialised and temporalised in a really interesting way, because of how Murata uses datamoshing and postproduction to question frames, and layers, by ‘glitching’ between those formal elements. And as a viewer of Pink Dot, your perception is founded by those slips between the spatial surface and the temporal layers. RM: Yeah, wow. I never looked at that work in terms of layers of editing. The vectors of these blocks that smear over the video, the movement of those macroblocks, which is what this video technologically is about, is also about time and editing. So Murata effectively emulates that datamosh technique back into the editing of the work before and after the actual datamosh. That is genius! DR: If it wasn’t for Pink Dot I probably wouldn’t sit here with you now. It’s such an important work for me and my thinking.

Working with Morehshin Allahyari on The 3D Additivist Manifesto has brought a lot of these processes into play for me. The compressed labour behind a work can often get lost, because a final digital video is just a surface, just a set of I and P frames. The way Murata uses datamoshing calls that into play. It brings back some of the temporal depth. Additivism is also about calling those processes and conflicts to account, in the move between digital and material forms. Oil is a compressed form of time, and that time and matter is extruded into plastic, and that plastic has other modes of labour compressed into it, and the layers of time and space are built on top of one another constantly – like the layers of a 3D print. When we rendered our Manifesto video we did it on computers plugged into aging electricity infrastructures that run on burnt coal and oil. Burning off one form of physical compressed time to compress another set of times and labours into a ‘digital work’. RM: But you can feel that there is more to that video than its surface! If I remember correctly you and Morehshin wrote an open invitation to digital artists to send in their left over 3D objects. So every object in that dark gooey ocean in The 3D Additivist Manifesto actually represents a piece of artistic digital garbage. It’s like a digital emulation of the North Pacific Gyre, which you also talked about in your lecture at Goldsmiths, but then solely consisting of Ready-Made art trash.

The actual scale and form of the Gyre is hard to catch, it seems to be unimaginable even to the people devoting their research to it; it’s beyond resolution. Which is why it is still such an under acknowledged topic. We don’t really want to know what the Gyre looks or feels like; it’s just like the clutter inside my desktop folder inside my desktop folder, inside the desktop folder. It represents an amalgamation of histories that moved further away from us over time and we don’t necessarily like to revisit, or realise that we are responsible for. I think The 3D Additivist Manifesto captures that resemblance between the way we handle our digital detritus and our physical garbage in a wonderfully grimm manner. DR: I’m glad you sense the grimness of that image. And yes, as well as sourcing objects from friends and collaborators we also scraped a lot from online 3D object repositories. So the gyre is full of Ready-Mades divorced from their conditions of creation, use, or meaning. Like any discarded plastic bottle floating out in the middle of the pacific ocean. Eventually Additivist technologies could interface all aspects of material reality, from nanoparticles, to proprietary components, all the way through to DNA, bespoke drugs, and forms of life somewhere between the biological and the synthetic. We hope that our call to submit to The 3D Additivist Cookbook will provoke what you term ‘disputes’. Objects, software, texts and blueprints that gesture to the possibility of new political and ontological realities. It sounds far-fetched, but we need that kind of thinking. Alternate possibilities often get lost in a particular moment of resolution. A single moment of reception. But your exhibition points to the things beyond our recognition. Or perhaps more importantly, it points to the things we have refused to recognise. So, from inside the iRD technical ‘literacy’ might be considered as a limit, not a strength. RM: Often the densities of the works we create, in terms of concept, but also collage, technology and source materials move quite far away or even beyond a fold. I suppose that’s why we make our work pretty. To draw in the people that are not technically literate or have no back knowledge. And then perhaps later they wonder about the technical aspects and the meaning behind the composition of the work and want to learn more. To me, the process of creating, but also seeing an interesting digital art work often feels like swimming inside an abyss of increments. DR: What is that? RM: I made that up. An abyss is something that goes on and on and on. Modern lines used to go on, postmodern lines are broken up as they go on. Thats how I feel we work on our computers, its a metaphor for scanlines. DR: In euclidean space two parallel lines will go on forever and not meet. But on the surface of a globe, and other, non-euclidean spaces, those lines can be made to converge or diverge. * RM: I have been trying to read up on my euclidean geometry. DR: And I am thinking now about Flatland again, A Romance in Many Dimensions. RM: Yeah, it’s funny that in the end, it is all about Flatland. That’s where this all started, so thats where it has to end; Flatland seems like an eternal ouroboros inside of digital art. DR: It makes me think too about holographic theory. You can encode on a 2D surface the information necessary to construct a 3D image. And there are theories that suggest that a black hole has holographic properties. The event horizon of a black hole can be thought of as a flat surface, and contains all the information necessary to construct the black hole. And because a black hole is a singularity, and the universe can be considered as a singularity too – in time and space – some theories suggest that the universe is a hologram encoded on its outer surface. So the future state of the universe encodes all the prior states. Or something like that. RM: I once went to a lecture by Raphael Bousso, a professor at Department of Physics, UC Berkeley. He was talking about black holes, it was super intense. I was sitting on the end of my seat and nearly felt like I was riding a dark star right towards my own event horizon. DR: [laughs] Absolutely. I suppose I came to understand art and theory through things I knew before, which is pop science and science fiction. I tend to read everything through those things. Those are my starting points. But yes, holograms are super interesting. RM: I want to be careful not to go into the wunderkammer, because if there are too many things, then each one of them turns into a fetish object; a gimmick. DR: There was a lot of talk a few years ago about holographic storage, because basically all our storage – CDs, DVDs, hard drive platters, SSD drives – are 2D. All the information spinning on your screen right now, all those rich polygons or whatever, it all begins from data stored on a two dimensional surface. But you could have a holographic storage medium with three dimensions. They have built these things in the laboratory. There goes my pop science knowledge again. RM: When I was at Transmediale last year, the Internet Yami-ichi (Internet Black Market) was on. There I sold some custom videos for self cracked LCD screens. DR: Broken on purpose? RM: Yes, and you’d be allowed to touch it so the screen would go multidimensional. Liquid crystals are such a beautiful technology. DR: Yes. And they are a 3D image medium. But they don’t get used much anymore, right? LEDS are the main image format. RM: People miss LCDS! I saw a beautiful recorded talk from the Torque event, Esther Leslie talking about Walter Benjamin who writes about snow flakes resembling white noise. Liquid crystals and flatness and flatland. I want to thank you Dan, just to talk through this stuff has been really helpful. You have no idea. Thank you so much! DR: Putting ideas in words is always helpful. RM: I never do that, in preparation, to talk about things I am still working on, semi-completed. It’s scary to open up the book of possibilities. When you say things out loud you somehow commit to them. Like, Trevor Paglen, Jon Satrom are huge inspirations, I would like to make work inspired by them, that is a scary thing to say out loud. DR: That’s good. We don’t work in a vacuum. Trevor Paglen’s stuff is often about photography as a mode of non-resolved vision. I think that does fit with your work here, but you have the understanding and wherewithal to transform these concerns into work about the digital media. Maybe you need to build a tiny model of the gallery and create it all in miniature. RM: That’s what Alma Alloro said! DR: I think it would be really helpful. You don’t have to do it in meatspace. You could render a version of the gallery space with software. RM: Haha great idea, but that would take too much time. iRD needs to open to the public in 3 weeks! * DR originally stated here that a globe was a euclidean space. This was corrected, with thanks to Matthew Austin.

The background to this research

Everybody loves giraffes, and god knows they've been covered on Tet Zoo enough times (see the links below). And something that's been mentioned many times is the alleged inability of giraffes to swim, or even to float. There are several specific comments on this in the literature (e.g., Shortridge 1934, Goodwin 1954, MacClintock 1973, Wood 1982); Crandall (1964) mentioned a case where a captive giraffe escaped from a carrying crate, fell off the end of a jetty, and immediately sank in the Hudson River (incidentally, dead giraffes have apparently been in the Hudson more than once: it is alleged that the river has, on occasion, been used as a dump for the corpses of zoo animals).

Why should giraffes be unable to swim? I'm extremely sceptical of such claims, given that other animals sometimes said to be unable to swim - like giant tortoises, pigs, rhinos and camels - actually swim just fine or even very well. Nevertheless, giraffes are such a strange shape that one can just about believe that their swimming and/or floating behaviour differs from that of other quadrupedal mammals.

And while it's possible to find reports and even images of giraffes wading [photos above below © Jeff Arnold] (Jonathan Kingdon notes that giraffes "will wade quite deep rivers" (Kingdon 1989, p. 325)), reports that describe them swimming don't exist, so far as I can tell. A few years ago, the excellent BBC series Big Cat Diary featured a scene where a group of giraffes tried to cross the Mara while it was in flood. The giraffes got about half-way across before turning back [two of them are at the turning-back phase in the adjacent still, © BBC], and at one stage were in water that submerged them right up to the bases of their necks. I thought at the time that these giraffes must have been swimming: I was so confident that I even mentioned this on the Dinosaur Mailing List back in 2000 (I now think it more likely that those Kenyan giraffes still had their feet on the riverbed: you can see this for yourself, as the footage is online here*). Several writers and researchers who have googled 'swimming giraffes' during the course of research have discovered my comment, and I've since seen it paraphrased in a few places (such as here at Telegraph.co.uk and on Focus magazine's Q&A page).

  • Thanks to Dartian for finding this video for me.

After seeing the Focus magazine piece (this was in 2008, I think), I came up with an idea. I knew that my august colleague Donald Henderson of the Royal Tyrrell Museum of Palaeontology - well known for his work on what you might call mathematic palaeontology - had produced a digital model of a giraffe for a previous project (Henderson 1999), and had been testing the buoyancy of some of his models in 'digital water' (Henderson 2003a, b, 2006). Could, I wonder, Don take his digital giraffe and drop it into digital water, and thereby test the hypothesis that giraffes cannot float, or cannot swim? This, my friends, is how papers are born...

Modelling a digital giraffe

To start with, it's clear that we wouldn't actually be able to fully test the swimming abilities of giraffes (given that we couldn't accurately replicate or estimate all the details of aquatic movement in a giraffe), but we could test the floating abilities, and hence indirectly test the potential swimming abilities.

Giraffes are complicated objects, and modelling them digitally is fraught with difficulty. A 3D giraffe model was generated via the digital slicing method described by Henderson (1999) (our model isn't definitely meant to depict any of the Giraffa taxa in particular; yes, we're well aware of the suggestion that the several 'subspecies' conventionally included in G. camelopardalis might warrant species status). Several things were done to make the model more like a real giraffe: ears, ossicones and the fleshy part of the tail were created, and a synthesized reticulated pattern was created because it made the model look so much better. Don has actually pioneered a very interesting technique for generating regularly spaced polygons and/or blotches - it has some really interesting implications that I can't discuss here (for more information, see Appendix A in Henderson & Naish (2010)).

Two details of a digital model are particularly important when testing simulated buoyancy: density and lung volume.

Giraffe limb bones are slightly thicker than those of other artiodactyls (van Schalwyk et al. 2004), so their density was set as being somewhat higher than the rest of the body (1050 g/l vs 1000 g/l). The giraffe's most notable feature - its neck - was set at 850 g/l, as is typical for hoofed mammals. As we'll see, the high density of the distal parts of the limbs and low density of the neck and head seem to have implications for the floating and swimming behaviour of giraffes.

The lungs of giraffes are peculiar in size and shape (as you'll know if you watched Inside Nature's Giants), and exactly how large they are has long been a point of controversy: estimates of their volume in an 'average' giraffe (of 1.1 tons) have ranged from a low of 10 litres (Patterson et al. 1957) to a high of 47 litres (Robin et al. 1960). By scaling up from a horse to a big, male, 1.6 ton giraffe, an enormous projected lung volume of 141 litres was obtained (lung volume is about 6 litres in humans). Projections of this size have long been thought to be erroneous, however (Stahl 1967). A probable lung size about eight times that of a human is generally thought about right... in which case about 48 litres is correct for a 1.1 ton giraffe; this scales to 74 litres for a 1.6 ton giraffe. Obviously, there's much uncertainty here and more data is needed.

Don also modelled a horse Equus caballus [shown here] as a control for the experiment.

Can a giraffe float?

Given that the horse model seems to accurately predict the real-life buoyancy of floating and swimming horses (Henderson & Naish 2010), we're fairly confident that the giraffe model mimics the real thing. By rising the simulated water level around the giraffe model [as shown in the figure below], it was found that an adult giraffe would start to float at a water depth of about 2.8 m. It seems that the hindlimbs would leave the substrate before the forelimbs, raising the possibility that giraffes in deep water might be able to pole themselves along with their forelimbs alone.

But if the water becomes deeper still, what happens when the giraffe lifts off the substrate and begins to float? In a simulated floating posture, the hips are higher than the shoulders and the heavy forelimbs and short body mean that the foreparts are angled downwards relative to the horizontal. In turn, this means that the neck is rotated downwards and has to be held near-horizontally and just at, or under, the water surface: so far as we can tell, it doesn't seem possible for giraffes to swim with the neck held erect out of the water. The horizontal neck posture then means that the head has to be held at a very awkward, upward-angled posture (assuming, of course, that the animal wants to keep its eyes and nostrils above the surface).

It's well known that the giraffe head - particularly that of old males - is dense-boned and fairly heavy, but the cavities in the head and the long trachea and oesophagus make the head and neck rather less dense than the rest of the animal (850 g/l vs 1000 g/l or more). The neck and head account for about 10.8% of the animal's total mass, but it seems that their low density actually prevents the animal's anterior part from being even further down in the water (Henderson & Naish 2010). The overall density of the giraffe is higher than that of the horse, making the animal closer to being negatively buoyant and also making it sit lower in the water than the horse model.

In conclusion, it seems that giraffes can float: there's no reason to assume that they might 'sink like stones', nor was there any indication from the model that it was particularly unstable and prone to capsizing. But the model's posture in the water is low and hardly ideal, and looks downright uncomfortable. What might this mean for swimming ability?

Bad at swimming, or really bad at swimming?

The high mean density of the giraffe and the peculiar and difficult horizontal-necked posture the model adopts in water suggest that giraffes would not perform well in water. A large amount of drag and rotational inertia also afflict the model: in fact, it suffered from 13.5% more frictional drag than the horse model (Henderson & Naish 2010). We also suggest that the unusual gait practised by giraffes may well impair their swimming abilities. Giraffes on land use a synchronous movement of the neck and limbs where backwards and forwards movement of the neck is closely linked to the limb movements. But, with its neck constrained to a sub-horizontal posture where little or no backwards and forwards movement is possible, a swimming giraffe cannot adopt a gait like the one it uses on land.

Quadrupedal mammals - like the horse - typically swim with a trot like that used on land, so it seems reasonable to assume that swimming giraffes should try and swim with a 'terrestrial'-style gait too. However, note that this argument isn't completely conclusive, because the swimming gaits of some quadrupedal mammals are very different from their walking or running gaits. Nevertheless, I still think that our assumption is a reasonable one.

Positioned in the water in an uncomfortable pose, afflicted with a relatively high mean density, suffering from substantially high frictional drag, and unable to raise and lower its neck and hence unable to adopt a synchronous gait, we conclude that giraffes would be very poor swimmers, and that it might be assumed that they would avoid this activity if at all possible. Looked at another way, we conclude that giraffes can swim, but not at all well [image below from wikipedia].

Does this have any implications whatsoever for anything?

Making predictions about the floating and swimming abilities of giraffes is fun, but does it have any wider implications? For one thing, it perhaps helps make the point that we're increasingly able to test questions in biology using computational models and simulation, rather than experimentation on real animals. In the case of the question "Can giraffes swim?", we just aren't able to use real giraffes, so our approach is - at the moment - the only one we can use to test it.

If giraffes do perform poorly in water - so much so that they avoid crossing large bodies of water should they need do - has this had any impact on their biogeography? If you look at maps of giraffe distribution - and specifically at the ranges of the different giraffe taxa - you'll see that, in places, rivers and lakes form what appear to be giraffe-proof barriers. The Zambezi and its tributaries might form a southern barrier to Angolan and Thornicroft's giraffes (Spinage 1968), for example, the Niger and Benue might have prevented the southern spread of the Nigerian giraffe (Hassanin et al. 2007), while the Nile and Great Lakes might have prevented gene flow between Kordofan and Nigerian giraffes (Hassanin et al. 2007) [figure below - from Brown et al. (2007) - shows the approximate ranges and pelage patterns of the extant giraffe taxa].

Unfortunately, we don't really know enough to be sure whether these distributional limits actually have anything to do with the ability or inability of giraffes to cross water. As we note (Henderson & Naish 2010), big rivers and lakes are formidable barriers to everything terrestrial, not just to clumsy swimmers. Furthermore, the biogeographical history of giraffes extends over many millions of years (and involves Eurasia, too), meaning that climatic changes, changes in drainage patterns, and the terrestrial movement of giraffe populations make it difficult to definitively link any aquatic barriers to giraffe distribution. Others have made similar comments (Cramer & Mazel 2007) [image below: awesome male Masai Giraffe G. camelopardalis tippelskirchi (or G. tippelskirchi), photographed at Lake Manyara National Park, Tanzania. From wikipedia].

Finally, this project is one of several I've been involved in that's gotten a bit of media attention; this attention means that the paper is going to be the subject of more content-free discussion on websites than is usual for peer-reviewed research. Let me assure all concerned readers that this research did not involve the frittering away of pennies otherwise allotted to cancer research or the detection of Earth-killing asteroids. As I've said before (and, given that this article is appearing on ScienceBlogs, I'm preaching to the choir anyway), it isn't widely realised how much work scientists do FOR FREE and FOR FUN, IN THEIR SPARE TIME. Rant over.

Oh, and having mentioned Inside Nature's Giants, it is my duty to inform you that series 2 starts on June 8th. Episode 1 looks at the anatomy of Carcharodon carcharias, the white shark. This is incredible news; I'll be writing about the series in due time.

<![CDATA[Myriahedral projection maps of the world]]> http://centripetalnotion.com/2009/12/10/10:21:55/

A new technique for unpeeling the Earth’s skin and displaying it on a flat surface provides a fresh perspective on geography, making it possible to create maps that string out the continents for easy comparison, or lump together the world’s oceans into one huge mass of water surrounded by coastlines.

“Myriahedral projection” was developed by Jack van Wijk, a computer scientist at the Eindhoven University of Technology in the Netherlands.

“The basic idea is surprisingly simple,” says van Wijk. His algorithms divide the globe’s surface into small polygons that are unfolded into a flat map, just as a cube can be unfolded into six squares.

Cartographers have tried this trick before; van Wijk’s innovation is to up the number of polygons from just a few to thousands. He has coined the word “myriahedral” to describe it, a combination of “myriad” with “polyhedron”, the name for polygonal 3D shapes.
