Halloweentown Jack-in-the-Box

I bought one of those foam pumpkins for this project. It also comes out every Halloween. I traced a photo from the film of this prop to make the templet then proceeded cut it out with a scalpel. I painted the inside of the pumpkin black and repainted the outside orange to give it a more 'realistic' look. I am almost finished with the box that it goes in. I hope to make it functional by adding a motor in the box that moves the pumpkin head up and down. I was thinking about using the guts of those Moving Chrismtas wire frame animal displays for it. Course getting one cheap it the only way to go.
