Ponoko - personal manufacturing platform
If you don't have access to a laser cutter, this is one of the best ways to see what you can do and try one out. For inspiration, you can check out How to make a laser cut lamp, which I encouraged them to post. It not only shows a cool lamp, but goes through the design process and using Ponoko's service.
So, check out their service and tell us what you think. The Ponoko guys are here on Instructables, and would love to hear your feedback.
