BumpTop, Pushing the Desktop Metaphor

Alranor writes "BumpTop is a new way of manipulating your GUI desktop with a graphics pen. Documents can be moved and piled (among other actions) as if they were real pieces of paper on a physical desktop. Simulated real physical interactions, such as documents pushing others out of the way as you move them around, are intended to increase the intuitiveness of the layout tool. Given the messiness of my desks at work and home, I'm not so sure this will work for me, but it's an interesting idea."
