Clay animation, or claymation, refers to a specific form of stop-motion animation where characters and objects are molded out of clay and then manipulated frame-by-frame to create the illusion of movement. Some synonyms for clay animation include claymation, plasticine animation, and clay art. Plasticine animation is another term often used interchangeably with claymation, as plasticine is often used in place of traditional clay due to its pliability and ease of use. Clay art typically refers to the sculpture and modeling of clay itself, rather than the animating process, but can also be used to describe the final product of a clay animation.
