This is a classic short film which won the Academy Award, and has a very interesting soundtrack to say the least:
The creator and composer is Norman McLaren, who apparently cut little wedges and nicks into the side of the film to create the score! I would be curious to know how he managed to do that and still create something as cohesive as this is. In any case, enjoy a bit of strangeness from 1952 -- I suppose his pioneering pitch-generation technique was revolutionary at the time.
