Looks like an interesting concept, but it appears to be just that, a concept. Very cool though.
In a lot of ways, it looks similar to BumpTop (http://bumptop.com), although without the physics.
I can't seem to find any way to actually install this - I'm guessing its just a concept instead of an actual desktop environment or wm. Pretty pointless if theres nothing beyond 'It would be cool if a computer behaved like this'.
