yndy: A paper Enigma machine.
As noted, it's a simplified version without ring settings or plugboard, but it's still cool. If paper doesn't do it for you, try Dirk Rijmenants' fully functional Enigma simulator for Windows. He also has a fully functional simulator for the US M209 cipher machine, based on the Swedish Hagelin C-38.
