You've probably seen this by now, but if you haven't, you should. BumpTop is a prototype of a new desktop metaphor for computing, and a pretty damn intriging one at that.
Update: Peterme isn't impressed. I don't think BumpTop is going to replace WIMP either, but there are certainly some applications where some of the BT ideas could be useful.
