USB Missile Launcher from ThinkGeek (discontinued) can pivot 180 degrees horizontally, and 45 degrees up. USB Missile Launcher stands approximately seven inches high, is gunmetal grey, with three 5 to 8 feet white foam spring-loaded missiles on top. The missiles are controlled by the included PC software, which when you press on big red shiny delicious button on screen, a missile will shoot. But too bad is that it’s not USB powered, instead it requires 3 AA batteries, which are included. However, you need to buy a new one once the battery life flat.
