Using Arduino and Processing, 4 players control fish which must eat to stay alive. As a fish eats one of 3 food items, it will grow and change depending on the type. Some food items make fish wider, some make them longer and a third gives them spikes with which they can cause damage to other fish.

Motion Fighter is an interactive game installation that utilizes a webcam and Processing.

Two players face each other, separated by a cloth on which the image is projected. The webcam, placed to the side of the screen, detects the motion of each player and creates projectiles from areas of high enough motion.
Players must then attempt to dodge their opponent’s projectiles.
