This is for the more artistic among us. Ponoko's site lets you design and build 2D objects online. You simply design your product on a piece of paper, take a picture of it and upload it to the site. Using laser cutters, Ponoko, then prototypes your design in a range of materials.

Huge amounts of fun to be had for adults and children. I wonder if I can design a bed laptop tray with this? Watch the fun instructional video they have.
