Adafruit is now offering a bionic eyeball module just in time for Halloween. The eyeball rolls in a nervous fashion in response to signals from a microprocessor. The eye itself is 3D printed out of thermoplastic and is customizable with paint and a permanent marker. The eyeball fits into standard 50 mm goggles and with only three triple A batteries you will be ready to rock and roll.
