paper stories

You see it all the time in the movies: someone finds a pile of shredded documents proving just how evil the evil bad guys is, takes a picture, and sends it to their lame computer geek sidekick. Much clicking of mice and typing on keyboards ensues, and lo, the documents are magically reconstructed. DARPA thinks this is cool and wants to make it happen for real.
Anyone who runs some kind of illegal business, needs a super fast way to destroy any evidence when law enforcement comes knocking at the door. Sure, a regular electric shredder works fine, but if you want your incriminating paperwork to disappear fast, it's much easier if the shredder is built right into the middle of your table.
