I built a rotating mirror a couple years ago to do the Haunted Mansion illusion where you project a ghost on the rotating mirror and it looks as if it's flying. I wasn't able to find a cheap slide projector though and tried to build one myself, but was unsuccessful and the project has since languished. Last week, however, I was able to score a super cheap digital projector and thought I might try to resurrect this. I figured though, since I'm no longer confined to a static image I might instead project either a simple movie in a loop or an animated gif. I looked into AtmosFearFX, but their movies were really much more complicated and detailed than what I was looking for. Anyone know where I might find something?
