Initials3D

This app carves your initials out of a cube of bits. But the sculpture is a little weird. You don't see all three letters at the same time. From the left you see one, from the top you see another, from the front you see another. I really can't describe it in words.

The digital sculpture that this app makes can then be sent along to a 3-D printing service (currently Shapeways.com). They'll mail it back to you so you can put it on your keychain, hang it from your mirror, or keep it in your pocket.
