>>5692985The zoetrope by itself is a rather simple device. It is merely a revolving cylinder, featuring a continuous sequence of images ordered by their phases of movement lining the drum interior. When rotated at rapid speed, a succession of images blur into the illusion of motion, of animation, of life. More sophisticated variants project the moving image via lanterns and a catoptric apparatus enabling easier viewing as opposed to slits or apertures, though the basic principle of operation remains the same.
