FlowingData has an article on the Fritz Kahn poster, Man as Industrial Palace. Now, this poster has been made into a video. Hit the site below for a link to the video.

In 1926, Fritz Kahn illustrated man as a working factory in his famous poster, Man as Industrial Palace. Tiny guys in each body system perform their own specific job. A camera man controls the eyes, groups of thinkers sit up top, and the guys at the bottom handle the dirty work.

Designer Henning Lederer brings the poster to life in animated and interactive form (below). I love the little guys working the switchboards.
