About this 3D model

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.http://www.youtube.com/watch?v=yvaW0t6TS_U&feature=youtu.be
