By the way, I done did it. I had toyed with the idea of trying to get the graphic I'd designed (my avatar) onto a bumper sticker or something. I figured a way to make it into a 4x6 laminated car magnet
Gonna get them up on ebay this weekend and see if I generate any interest
Here it is on a license plate so you can judge size (the plate's a friend's who wanted the number blurred...)
