If you'd much rather spruce up people than products or spaces, the Ponoko 10-day Jewelry Design Challenge should be right up your alley. You've got from March 1st to March 10th to design kick-ass jewelry for production on a laser cutter. It can be a single 2D piece or something more dimensional and composed of several parts.

The top 25 entries will be manufactured for free and submitted to the final round. The top 10 designers will each receive US$300 and the grand prize winner will get a sweet US$1,000.
