Gizmo - A compilation of man inventing strange contraptions from the 1920's through 1950's. Comedy. Answered
It starts off a bit slow but there are at least fifty really amazing clips. Sort of makes you think there's nothing new.
IMDB description: A documentary about some of the thousands of inventions that did things we never thought needed doing, or in ways we never considered doing them. A respectful, yet humorous tribute to the inventors whose vision, however far-reaching, was just a little off the mark.
