A zoetrope is a device the produces a illusion of action from a rapid succession of static pictures.
It consists of a cylinder with slits cut vertically in the sides. Beneath the slits, on the inner surface of the cylinder, is a band which has either individual frames from a video/film or images from a set of sequenced drawings or photographs.
The zoetrope was invented in 1834 by William Horner, who called it a "daedalum" or "daedatelum” (meaning wheel of the devil!)
The faster the rate of spin, the smoother the progression of images.
The illusion of motion is gone. The slots of the zoetrope simulate flashes of light, creating a strobe.
