Think of it as the future of today's paper.

The Palo Alto Research Center (PARC) and parent company Xerox are experimenting with a type of paper and a complimentary printer that would produce documents that fade away after 16 to 24 hours. A restaurant, for instance, could print its daily specials on a piece of paper, attach the pieces of paper to menus, and then collect the sheets of then-blank paper in the morning to run through the printer again.

How does it work? The paper is coated with photosensitive chemicals that turn dark when hit with UV light.
