Hi, at my school we are currently in the design stage for on musical "The Music Man". One scene is that there are people sitting on a train car which is supposta be moving, I was trying to figure out if it would be possible to create a moving landscape behind the windows of the train car to give the illusion that the train car was actually moving. One idea I had was to use some sort of painted fabric sewn like a belt for a belt sander turning continuosly via a low speed motor. Any Ideas?
