RotArcade

RotArcade from KaiGossner is a combination of the propeller clock and Arcade. 20 light emitting diodes spinning at about 3000 rpm will generate the illusion of a stationary (360 degrees) 512 * 20 pixel computer screen. Fast (P)uls (W)idth (M)odulation is used to create 8 different shades of gray. RotArcade can be controlled by a computer using a simple infrared link, but can also play BlinkenLights and Arcade movies without Computer connection from the internal 128KB flash memory.
