Laser Spirograph (meant as a tree topper)
DO NOT USE A LASER STRONGER THAN 5mW (Class IIIa) FOR THIS DEVICE! This has not been tested by anyone to be safe for lasers stronger than 5mW. If the motor drivers stall and the laser happens to be pointing at your eye, you will not see out of that eye any more. This is serious, folks!!!

Two vibration motors - you can pick up at Radio Shack. https://www.radioshack.com/products/radioshack-3vdc
