The Enigma cipher machine was a very cool electromechanical device for producing polyalphabetic ciphers that reached it’s heyday during World War II. The original surviving devices are all in museums or private collections, but you can make a paper version. This site: http://mckoss.com/Crypto/Enigma.htm will let you print one out and play with it.
