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 :)
Step 1: Pick 2 or 3 views or images for each perpective.
Step 2: Extrude first view
Step 3: Sketch your second image onto the plane perpendicular to the first
Step 4: Extrude the negative of the second sketch as a cut and you're done!
There you have it! Now you have a solid model that can be 3D printed.
I still remember how mind-blown the first time I saw one of these. Now with easier access to 3D printing and some basic CAD skills, I can now create my own, personally customized, multidimensional models, and so can you!
Have fun and don't forget if you don't have CAD software and want your own sculpture, comment below and I will try to create some models for the first couple of comments.
