The computer-controlled USB Cannon from Vat19 is basically “a self-propelled, desk-mounted artillery battery with two axes of movement — simply use the arrow keys on your PC to track down that bogey.” Product page. Video after the break.

The USB Cannon has a range of approximately 10 feet. Your ordnances (that’s “grunt-speak” for missiles) truly come flying out of this thing.
