BumpTop is a fun, intuitive, 3D desktop that keeps you organized and makes you more productive. It combines the look and feel of a real desk with the power of your PC. You can pile your files, flip through websites and toss your photos up to Twitter or Facebook quickly and easily, right from your desktop. Advanced search and sort capabilities make sure you can find your files when you need them. Personalize your desktop with custom themes, sticky notes and photo slideshows and turn your desktop into a useful, fun space instead of a graveyard of lost or forgotten files. An upgrade to Pro version will add such features as unlimited sticky notes and enhanced productivity and piling features.
It seems Google has acquired all rights to the software so it will no longer be for sale. My guess is we may well see BumpTop as an integral part of the Google operating system??
