If you are looking for some exciting new software then BumpTop is what you need. The movie above is a great example of how it works and there are higher quality videos available (MOV or WMV) for those people with really high-speed connections.

When I saw the demonstration video I was endlessly amazed. It looked like it was so much fun that it should be a video game. The only downside is that the software is not available to be downloaded…yet! Hopefully they will let everyone have some 3D fun on their desktop soon.
