AT&T Tech Channel
A 1982 AT&T Bell Labs film for students about the Unix system and how it can be used practically. It includes Lorinda Cherry building a talking calculator by piping together Unix commands, and a spell checker made from Unix utilities.
HN commenters recommend it as a demonstration of the Unix philosophy, with small tools composed through pipes.
