That's by far the best looking and most interesting/informative Enigma sim I've seen! I used to link to a different Enigma sim on my "Further Readings and Fun" (
http://www.dtek.chalmers.se/~d97jorn...rreadings.html ) page of my "eMail Encryption for the Lazy" site, but I just updated the page to link to your site instead.
Thanks for providing the site and the sims!
