Phantom Keystroker prank device

From ThinkGeek, this $25 tormentor:
200803191019 The Phantom Keystroker may look like a harmless circuit board, but it's actually a devious contraption of unlimited office-based torture. Simply discreetly attach the Phantom Keystroker to any extra USB port on your victim's computer, no drivers needed. The Keystroker emulates a keyboard and mouse and periodically makes random mouse movements and types out odd garbage text and phrases.
