Claire Parker

Claire Parker was an American engineer and animator. A graduate of MIT, she invented the Pinscreen, a vertically mounted grid of between 240,000 and 1 million sliding metal rods that are first manually pushed into position to create lit and shaded areas, then filmed frame by frame. While the hand-operated, mechanical Pinscreen superficially shares characteristics with early optical toys like the zoetrope, it is distinguished by being one of the first devices ever to produce animation by reconfiguring a set of individual picture elements, later called pixels. A model with sufficient pin "resolution" can be used to create a Pinscreen animation of photorealistic images, a painstaking process analogous to modern pixel art.
