BumpTop is a 3D desktop user interface inspired by real desks using physics, multi-touch gestures to drive towards a more expressive, human vision for computing. You can download it for Mac andWindows or build on top of the source code. Learn more by watching the TED talk
BumpTop started with a master's thesis and a YouTube video in 2006. A group of University of Toronto grads explored combining 3D user interfaces, touch and physics in innovative ways to push user interfaces forward, beyond the "cave painting" era of point-and-click. BumpTop became a viral hit, gaining millions of views, a supportive fan community, a TED talk and was ultimately acquired by Google to join the Android team.
