I played around in Solidworks, a CAD package, and created my own "perspective" sculpture of my signature. I then produced it with a 3D printer.
For those interested, comment with your email address, and I will create a custom model of your name, which you can 3d print. If you don't have a 3D printer, I can upload it to shapeways.com where you can get it printed. I said I would do this for the first three, but if I have time, I will try to do this for as many of you as possible. Just comment :)
