If anyone has seen the movie "Sleepy Hollow" starring Johnny Depp, you must have noticed the scene where the little boy lights the candles in the punched tin can, the can starts to spin from the heat of the candles, and the punched holes in the can are shapes, a cat, a witch, a tree, etc, and these shapes are actually projected onto the walls, projected and spinning very, very slowly. As you know this movie is set in the late 1800's, so it is not any kind of electrical thing. I would love some ideas on how to make one of these, I don't even know what they are called, I have looked for one on ebay and here on instructables....I've been calling it a "shadow projector" but that probably isn't right. It is an awesome little contraption, great for halloween or anytime, depending on the theme of the pictures punched on it. Any ideas/photos/clues would be appreciated. Thanks!
