Jim Henson's "Time Piece"

In 1965 Jim Henson produced a short film featuring a Leroy Anderson-style "found sound" composition. This experimental film starts with a human heartbeat and moves outward to a clock, a bird, city streets, an office, a factory, and so on. The film was nominated for an Academy Award, and premiered at the Museum of Modern Art.

Special bonus: keep an eye on the credits, which thank Frank Oz(nowicz), who appears briefly as a messenger boy. Read more about Time Piece at Muppet Wiki.
