Joshua Noble, Martin Fuchs, and Philip Whitfield built "ReceiptRacer", a game that can be played on a receipt printer. It's like a classic arcade racing game in which the player must drive down a twisty path without hitting obstacles. A light moves over the continuously printing surface, representing the player. Sensors detect if the player has collided with any obstacles and end the game. Link -via Nerdcore | Joshua Noble's Website
