For more than 50 years, Art Clokey has worked with clay to produce works of art that form a catalog of "firsts" in the medium of film. He made the first music video, Gumbasia, in which colored clay shapes moved and transformed to the rhythm of jazz. He was the first to introduce the use of clay models of objects, animals and people in television commercials. He was the first to develop claymation techniques and the first to use them in full length feature films. He invented trimentional animation based on kinesthetic principles, and it became the signature of his career.
