Idea

These Eye-movement plans use stepper motors and motor-driver circuits to make the eyes move back and forth. You can easily substitute small air cylinders and solenoid valves for the motors which will reduce heat build-up. The relays will then trigger the electric valves causing the cylinder to push and pull at the eye mechanisms.
