Cute and clever. SmoothTeddy is a 3D sketch-based modeling tool, designed originally to help design stuffed animals. Developed in Java, it allows you to draw a sketch and the program turns that into a rotating 3 dimensional object. There is a video demo available for you to examine here and you can download the software here. I gave this a try on my Tablet PC and it works as advertised and is indeed quite clever.
