BumpTop is a GUI replacement for Windows and Mac. Sound regular? No. BumpTop is not your regular "desktop" interface. BumpTop's interface is all 3D and physics based and multi-touch enabled! It used to be available in two versions, free and paid, until Google acquired it. The last downloadable app from BumpTop's official website was on May 2010. PS. why ISI has no general chit chat forum by the way? EDIT: thanks to the internet, I still can download it from Chip.eu website.
