For engineers, designers, and other persons who love, love love complexity, it’s almost always a good time to go look at some drawings by Heath Robinson.
However, evidence suggests that his heirs are a bit on the litigious side, a bit demanding perhaps that Internet sites not show Heath Robinson’s wonderful drawings. So all we can suggest is that you might want to go searching the vasty depths of the Internet, and see if you get lucky and see any drawings. They are worth the search effort.
