This challenge is sponsored by our friends at Upverter who make a free, and easy-to-use, online prototyping tool.
It was tough picking a winner, and we decided to have two winners tied for first place.
Unfortunately, we didn't get enough entries to manufacture kits. However, the folks at Upverter were very amazed by all of the entries, and would like to send everyone who entered a T-Shirt.
1St Place - Tie!
