I'm hoping that this is on-topic for the list... Enigma Simulator - 1.1 simulator of the Enigma cipher machine with Steckerbrett Enigma Simulator is a program that simulates the use of Enigma ciphering machines that were commonly used by Nazi Germany during World War II. It enciphers text exactly the same as would a real Enigma machine. Now Enigma Simulator also includes the much anticipated Steckerbrett (plugboard). What's new in this version: -Steckerbrett (plugboard) -Universal Binary -Minor Visual Enhancements -'Reset' option added under 'Edit' menu (or use Command-R) -File Size Decrease (0.25MB off download and 1.2MB off Application file) -Minor spelling corrections http://www.versiontracker.com/dyn/moreinfo/macosx/32862 This software is for the Mac only. I suppose there must be a PC version out there as well... Enjoy! Al Phila, PA
