Sally Cruikshank is an American cartoonist and animator who worked on Sesame Street, and developed a very distinctive psychedelic aesthetic in her own animated shorts and painting. I'm posting some of her artwork here, as well as two films, 1975's Quasi at the Quackadero (inducted into the National Film Registry) and 1978's Make Me Psychic. These cartoons are wonderful; they really move in a very surreal, psychedelic style all of their own. I'd love to see them in higher quality.
