How does a kinetoscope work?

the kinetoscope was the precursor to the modern motion-film projector. it created the illusion of a moving picture by rapidly passing a film "between a lens and an electric light bulb while the viewer peered through a peephole. Behind the peephole was a spinning wheel with a narrow slit that acted as a shutter, permitting a momentary view of each of the 46 frames passing in front of the shutter every second." check out: http://www.britannica.com/EBchecked/topic/318211/Kinetoscope
