This is my first prop build. The growling will be louder, my baby was asleep when filmed. Right now its only motion control triggered, using motion sensor hack along with old comp PSU to control a bunch of relays. The most trouble some spot would have been trying to figure out how to get the wiper motor to stop in its resting spot. I only used white lights as I don't have time to wire up my color leds the way i want. Anyways here is the link, I hope you like it.
