Inspired by 3D zoetropes like Pixar's Toy Story zoetrope and John Edmark's Blooms, this was an attempt to create something similar on a webpage with the browser's frame rate acting like a stroboscope. Here, a circular image is rotated by a given angle between each frame. Use the +/- buttons (or the A/Z keys) to control the rotation speed.

Since the phenakistiscope and the zoopraxiscope also used spinning discs (and slits to create a succession of 'frames'), the discs for these 19th century devices lend themselves well to be animated here too.
