BumpTop, the (multitouch) slippery desktop

By John Bowman, CBCNews.ca.

More than three years ago, when I first starting writing about tech for CBCNews.ca, I wrote about a computer interface called BumpTop, which took the desktop model to the next level, giving files shape, weight and physics.

Back then, BumpTop was using pen-based computing, but now, it's updated and incorporates the multitouch support that Microsoft added to Windows 7. The multitouch adds more gestures to the BumpTop tool kit, including scrunching groups of files into piles, nudging files around with the edge of your thumb, and zooming and cropping photos.

Anand Agarawala, who helped develop BumpTop at the Dynamic Graphics Project at the University of Toronto, has a new demo up on YouTube showing off BumpTop's new features.
