BumpTop: A realistic 3D desktop

BumpTop is a crazy but simple idea.
Why losing "realistic" things of our desktops like making piles of books, magazines, pushing things, and such? Just develop a physics system, a small 3D engine and some cool mouse-drawing commands (like in Black & White videogame, you "draw" things that act like commands). Is not easy to explain but you can watch the video. I don't know if this is more "natural" or not than normal computer desktops (whenever Linux, Windows or Mac ones), but at least is some fresh air...
