I saw this on Digg (http://www.digg.com/):
T.E.D.D.Y. (http://lazyrussian.com/2006/09/15/freaky-friday-episode-3-teddy/)
It's a really cool applet that takes 2D drawings and converts them into 3D interactive renderings. Rather than try to describe the features, I'd recommend just watching the video at the above link. I was really impressed with the 3D color renderings at the end of the video. If you're interested and want to try it for yourself, click here.
