BumpTop With Multi-Touch: The Future Of UI?

From I4U News -

BumpTop is a graphical overlay that organizes your computer like an actual desktop. It is the first UI that fully takes advantage of the touchscreen, especially multi-touch functionalities. It includes several new patented gestures, some of which (like 'scrunch') use all of your fingers.

It is presently compatibly with Windows 7 only since the OS is one of the few with touchscreen support. But at least BumpTop's basic version is free and only lacks a few features like the ability to 'toss' files onto USB drives and flip through piles. The complete version, BumpTop Pro, is also affordable at only $29.
