Thaumatropes were popular toys in the 19th century. They are made of a disc with different images on the two sides. Rotating the disc very fast, the two images “combine” to make one. This happens thanks to the so called persistence of vision. Animation uses a similar effect to create a video out of a series of frames. Check zoetrope or stroboscope light for more insights!
