Transformer medallions! On the .eps there are 8 of them 4 small and 4 medium sized. Very cool for the Transformer lover. You can download the .eps. Or you can get the .svg from the Ponoko blog and customize it yourself to your liking. The design is made using a heavy etch into the acrylic. I'm not selling these, you'll have to make your own. I'm not worried about infringing copyrights, I'm worried about Optimus Prime coming down and kicking my butt. This is a pretty fun school holiday project, my kids were really excited about doing it. We used Inkscape for the design.
