Louis Le Prince’s Film Spools

Origins
Le Prince pioneered moving pictures before Edison had even heard of them and was only prevented from patenting them because of his unexplained disappearance from his train carriage in 1890, a year before Edison would go on to patent the concept.

Effects
Watching the first (a film of his family at Oakwood Grange) will transport the viewer into the film, essentially imprinting them onto the film. Rewinding the film will release them. Watching the second (a man playing an accordion) has no known effects, but is kept for potential safety reasons.
