Remember that optical illusion, the one with two faces that turn into a vase? If you have the money TurnYourHead will create a wooden Pirolette -- a silhouette of your face engraved in wood. It'll only set you back $250.

If that's too extreme for you, I have something, well, more extreme. For about $8700, you can buy a VersaLaser, a USB laser printer that burns images on a variety of surfaces. Create your design in, say, Word or CorelDraw, and burn substances such as wood, plastic, stone, glass, and metal. Me, I'll stick with my Brother laser print, thanks.
BTW, while doing research to find the silhouette illusion, I bumped into this bizarre, anomalous motion illusion. Weird.
