A zoetrope is a device that produces the illusion of motion from a rapid succession of static pictures. The term zoetrope is from the Greek words ζωή (zoē), meaning “alive, active”, and τροπή (tropē), meaning “turn”, with “zoetrope” taken to mean “active turn” or “wheel of life”. The zoetrope consists of a cylinder with slits cut vertically in the sides. On the inner surface of the cylinder is a band with images from a set of sequenced pictures.
