Those who grew up in dark and dank arcades will definitely remember the trackball which was used in the classic Missile Command game. Somebody in Japan decided to cook up a fully metal keyboard with a similar trackball, christening it the Fullmetal KB+TB. The dimensions of this non-plastic keyboard measures 392mm x 110mm and comes with a 2mm keystroke. It is connected to your PC via USB, and was originally designed to be used in industrial environments where something durable and cleanable was requiered. You can always pick one up for yourself for approximately $450 after conversion and use it to bonk any irritating colleague over the head.
