Many years ago in England, probably the late 60' or early 70's, the Harwell club showed the 'Ten Best' and one of the films was called 'Inside 4 minutes'. Basically it showed components of a clock in an exploded view. It always fascinated me and I have never seen it again. I looked through the IAC catalogues but could not find any reference to it and an internet search never turned anything up either.
Does anyone know anything about this short film?
