A piece of 35 mm. film found on the road in Bandra, Mumba, was looped across the room. The piece is 60 seconds and about 90 feet long. The film is a release print (for showing in cinema halls) of a TV serial promo.
You could follow frames of the film as they slip by at 1.5 feet a second.
Or, you could watch the film by interrupting the projection beam with your body, or other surface. Normally the projector is beaming the image into thin air. A webcam-based tracking system turns the sound on when the image froms on a surface. The focus distance is about two feet.
