Giving Artists New Tools Through Science And Technology

  October 12, 2014 ,

Building connections between seemingly disparate areas is one of the joys of being an artist. It’s also one of the biggest challenges. Conceptually, artists are trained (or train themselves) to look at topics from multiple angles and to build relationships that express the nuances of the proverbial “human condition” (one of my least-favorite artspeak terms, though it seems appropriate in this context). We take input from the world around us, process it through the lense of our personal experiences and knowledge, then spit it out in some novel way as artwork. Art schools are generally pretty good at giving artists artistic tools, but the focus tends to be on traditional art-making practice and thinking. Even new-media programs seem to focus on accepted art and design technology, such as Adobe Photoshop and the like. But what happens when an artist wants to expand their research into scientific fields, or access big data? The tools are out there, but the learning curve is so steep as to be seen as insurmountable. I’ve heard from multiple artists that they’d love to access primary sources of information, but dont know how or where to look. Consequently they end up relying on possibly inaccurate second- or third-hand information, with the caveat that it’s okay because it’s art, not science. To a certain extent that’s true: (probably) no one’s going to die if an artist uses bad or incomplete data. However, art can expose and educate us to experience and information in ways that no spreadsheet … Continue reading

3D Printing and the Art/Kitsch Divide

  October 9, 2014

That the debate over the art/kitsch divide has been theorized since at leat the 1930s shows that the supposed divide is arbitrary and the argument then breaks down into relativism. Like industrial culture production, the argument itself is of itself. To exist, it must already belong to the existing argument, otherwise it has no historical reference and the argument collapses. Unlike craft, kitsch cannot be defined by the intent of its creator. It is an outward-inward categorization that ignores embedded meaning planted by the creator. It is instead demarcated by an outside observer, who judges it to have no “pure” cultural value. Whether this is due to funcionality, quantity, or aesthetics, the judge claims it lacking in qualities needed to elevate it into true art. In modern times, the art/not art battle rages on through technology-based art. The industrialization of culture, specifically post-war culture, wherein normative benchmarks measure the acceptable deviation range allow for new correlaries through technology. What once was mass-produced physically on assembly lines is now (theoretically) endlessly able to reproduce itself through digital copies. This includes pixel-based images as well as digital-physical production methods, such as 3D printing. In the mid-20th century, artists avoided the production of kitsch, but since artists like Jeff Koons and Damien Hirst began to break the normative benchmark by intentionally producing “non art,” the range of acceptable mutation has grown almost to the point of meaninglessness. 3D-printed art relies almost entirely on the intent of the creator to define it as pure art … Continue reading

Deliberation Mapping – Shaping Online Discussion

  September 22, 2014

A quick previsualization of what a deliberation map may look like as a viewer scrubs through the timeline. One of the projects I’m most excited about is the Deliberation Mapping project. The general idea is to create a new interface and toolset for professors and students to engage in an online discussion or deliberation in a way that more closely resembles the non-linearity of in-person discussions. Online conversation, in its currently widespread adopted form (with occasional variation) is a linear stacked-reply system. Think your average comment system. Or Facebook. Each thread is placed below the previous based solely on a time hierarchy, with little control given to the participants for shaping the discussion. Every reply is given the same weight as every previous reply. Some commenting systems allow for crowd-sourced relevancy triggers such as the Like button or Up/Downvote button. This works well in terms of allowing a participant to see what posts are most preferred by the participants, but it doesn’t necessarily allow for the original poster to determine which posts are most relevant to the original thought. Thread hijacking can occur frequently where a troll can derail the conversation just for fun. What we’re looking to do is to give both the students and professor a time-based non-linear deliberation map of a conversation. Instead of linear threads, we use nodes. This allows for multi-dimensional replies and cross references. For example, in an in-person conversation with a group you’d listen to multiple comments then reply to all of them … Continue reading

3D Printing and the Accuracy Problem

  September 8, 2014

Tea, Earl Gray, Hot Star Trek made us think that the advent and widespread consumer adoption of 3D printers would soon have us calling out, “Tea, Earl Gray, hot” and like magic the item appears. Unfortunately, the current state of the technology is far from magic. They’re clunky, complicated to operate, difficult to calibrate, and are constantly requiring fixing or tweaking to keep them running smoothly. Occasionally, things go well, and while many manufacturers are coming closer to the holy-grail of the 3D-printer-as-appliance, more often as not you’ll end up fiddling with something on the machine when things start to go bad.  You’re also limited by two other factors: material and accuracy. While industrial machines are close to being able to print fantastic things like human organs, consumer printers are usually relegated to plastic: either ABS (think LEGO bricks) or PLA. PLA is becoming the dominant material for consumer machines because it doesn’t require a heated build platform to prevent warping (ABS suffers from  temperature differentials while cooling, causing lower layers to shrink more quickly while upper layers are still warm, curling edges). It’s also biodegradable and made from plants, so it’s more eco-friendly. 3D printers work through a process called fused-deposit modeling (FDM). Plastic filament is heated and then extruded through a nozzle in little spaghetti-like threads, building up forms layer by layer. The smaller the distance between layers, the smoother the surface appears. Example of layer heights Accuracy isn’t much of an issue for the typical hobbyist, it … Continue reading
