Animated Halloween Prop

I created this to be a prop in a haunted house. The idea was inspired by other animated Halloween props I have seen at various stores, and by the movie poltergeist.

I have posted a YouTube video showing it in action, plus some of the behind the scenes stuff from the build. Unfortunately I don't have any time-lapse of any of the prints.
