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.
