Wallbreaker Halloween Prop with a Wiper Motor

This is my second wallbreaker ghost. I built my first one 4 years ago after finding an AWESOME tutorial over at Johnny's Ghost. It was powered by a reindeer motor, and was rather weak; the motor couldn't handle the forward/backward motion of this prop due to the weight on the head. So this year I rebuilt the entire frame and installed a wiper motor and a prop controller. I lightened up the weight of the head by using a wire frame head instead of a styrofoam one. His green eyes are LEDs powered by a 9 volt battery. I call him Wally. He's still unclothed so you can see his inner workings.
