Protein synthesis on the quadrangle: where can I find the movie

IIRC, an outstanding short film was made in the late '60s or early '70s illustrating protein synthesis in which dancing Stanford students portrayed nucleic acids and puffs of smoke the conversion of ATP to ADP. Does any know if this film might be available (for free of course) on the web?

Sounds like a must see. Please oh please somebody find this thing.
