A Paper Enigma Machine!
This is the coolest thing! We compared the output to this Flash version of the enigma and it was identical!
Towards the bottom of the page it mentions cutting slits so the rotors stay in place and are easier to push/pull as you work through it. I did this and the results are great. It works really well and once you get used to it you can encode a letter fairly rapidly.
One thing to note: Be sure on your first encode that you move the right rotor up one before you encode the first letter! We missed this part. The starting position assumes you'll do that first.
XZPHS!(I-II-III, SAC) ;) (I used the paper version and then confirmed with the Flash version, and it was correct and the same, once again.)
I think it's cool how it's reversible. In the above example, E becomes X in the starting position and X becomes E in the starting position. It wouldn't work without that, but it's still cool.
Enigma (done in Flash -- a bit slow)
