Eadweard Muybridge's Zoopraxiscope

Eadweard Muybridge was a photographer whose innovations helped create filmmaking of today. His set of photographs, Sallie Gardner at a Gallop, helped prove that a horse will have all its hooves off the ground at sometime. He also shot and killed his wife's lover, the jury calling it a justifiable homicide. The zoopraxiscope lets anyone who spins it move up to several feet a second, leaving a visual gap of the person's figure to anyone observing them. If they think someone they are personally close to is being threatened, they will go to extreme lengths to protect them.
