Smell-O-Vision is a system that released odor during the projection of a film so that the viewer could "smell" what was happening in the movie. Created by Hans Laube, the technique made its only appearance in the 1960 film Scent of Mystery, produced by Mike Todd Jr., son of film producer Mike Todd. The process injected 30 odors into a movie theater's seats when triggered by the film's soundtrack.

The Nimatron was an electro-mechanical machine that played Nim. It was first exhibited in April–October 1940 by the Westinghouse Electric Corporation at the 1939-1940 New York World's Fair to entertain fair-goers.

Derr, the device was a non-programmable digital computer composed of electro-mechanical relays which could respond to players' choices in the game in a dozen different patterns. The machine, which weighed over a metric ton, displayed four lines of seven light bulbs both in front of the player
