Animated GIFs have had a new lease of life and are bursting onto our screens at the moment ever since Facebook has enable them on their software, but did you know that this type of animation had started long before any computers were invented?
The phenakistoscope used a spinning disc attached vertically to a handle. Arrayed around the disc’s center were a series of drawings showing phases of the animation, and cut through it were a series of equally spaced radial slits. The user would spin the disc and look through the moving slits at the disc’s reflection in a mirror. The scanning of the slits across the reflected images kept them from simply blurring together, so that the user would see a rapid succession of images that appeared to be a single moving picture.
And although Plateau is credited with inventing the device, there were numerous other mathematicians and physicists who were working on similar ideas around the same time, and even they were building on the works of Greek mathematician Euclid and Sir Isaac Newton who had also identified principles behind the phenakistoscope.
