Bumper Sticker Maker
Your very own bumper sticker maker! Prints out your own designs that you can slap on a car or sell. Hell, you could start a little garage business and make some money on the side.
It has single "color thermal transfer printing capability", and ethernet to connect to your computer. You can use your own graphic design software (i.e. Photoshop) or use the built-in software (which is probably rather basic, but it would get the job done).
