Sand animation is the manipulation of sand to create animation. In performance art an artist creates a series of images using sand, a process which is achieved by applying sand to a surface and then rendering images by drawing lines and figures in the sand with one's hands. A sand animation performer will often use the aid of an overhead projector or lightbox (similar to one used by photographers to view translucent films). To make an animated film, sand is moved on a backlit or frontlit piece of glass to create each frame.
Techniques for animating with sand were pioneered by Caroline Leaf when she was an undergraduate art student at Harvard University in 1968. She created her first film, Sand, or Peter and the Wolf (1968), by dumping beach sand on a light box and manipulating the grains to build figures, textures and movement frame-by-frame. In the 1970s, Eli Noyes, another Harvard graduate, created the noted Sandman short film (1973) and the Sand Alphabet (1974) which became a feature on the children's educational television program Sesame Street. In 1977, The Sand Castle by Dutch-Canadian animator Co Hoedeman won the Academy Award for Best Animated Short Film.
