Quick Summary

The phenakistoscope is an optical toy that creates the illusion of movement. It consists of a disk with images arranged around the center. Radial slits near the edge allow viewers to see these images in motion when viewed in a mirror. This device, developed around 1832, exploited optical phenomena like persistence of vision and the phi phenomenon, which allow the brain to perceive continuous motion from a rapid succession of still images. The phenakistoscope is considered a precursor to modern motion pictures and is related to other early optical toys like the zoetrope.123
