Ok, this thing is cool, and they wrote a paper. Where do I get the code? It's a bit ironic to use the tagline "What if every GUI were open source" and not link to the code.
You could always email the author. Often times academic code is slow to be released because the types of things that tend to be thought of as required for software release (documentation, install help, bug fixes, coherent code organization) simply aren't there. The reward system set up by academia doesn't place value on those types of things, so it takes a long time to get them done in your free time. The result is people are hesitant to release their code because they know it will likely be difficult to put to "real" use without heavy refactoring.
