USB tank

In the world of pointless USB devices there have not been many better than the USB humping dog from a few weeks ago. Well this USB tank comes pretty damned close. Basically you take a remote control tank jazz it up a little bit so the controller can be used via USB, fill it up with little plastic rockets that fire up to 20 feet (with a strong tail wind) and set it loose on the office. Although it would be mildly amusing for about 2 seconds if someone bought one of these into work I'd be keen to stomp all over it.
