here's an announcement of the 3D printing pioneers Ponoko:
"You can now turn digital photos of your hand drawings into real life products simply by uploading them to the Ponoko website.
This means you do not need to use graphics software to make something. This significantly lowers the entry barrier for all creative people who can hand draw using pen and paper but do not know how to use design software.
See how it works!
You can turn a photo of your hand drawn design or any jpg, gif or png file into the real life thing here: http://www.ponoko.com/photomake
