I remember watching this movie (WARNING: link to a large file) during my sophomore year of college. It now appears that some folks at Kenyon College plan to do a remake. For those of you too lazy to follow the links, the movie depicts protein synthesis using people acting out the roles of mRNA, tRNA, amino acids, ribosomes, and other assorted players. And it was made in 1971. And it involved interpretive dance. And hippies. Good shit, yo.
