Science in GIFs: Eadweard Muybridge's "zoopraxiscope"
Muybridge was a photographic pioneer who was obsessed with using photography to capture things that happen too fast for the human eye to see. In 1878, he famously showed what a horse looks like in full gallop by producing a series of timed pictures. Then he put them on a zoetropic wheel, spun it around, and produced a tiny looped video. It was the world’s first animated GIF. Via
