ComputerWrist

A game of Paddle War being played on the ComputerWrist.

The ComputerWrist is the name of the computer Keen carries on his wrist. It appears to use at least some parts from an Atari Lynx handheld console. Keen's arm can clearly be seen behind the ComputerWrist in the picture on the right (however, it is not white, instead being flesh-colored). The ComputerWrist is the player's main interface to the game, and it has extra features such as being able to play Paddle War, which is very useful to pass the time on long space journeys.
