Yes I have solved your pretty pretty puzzle yet. The Enigma machine and rotors as a flash program is really cool. I was looking for one after my visit to Bletchley Park during a trip to London. I never found one back then (a few years ago). I became an even biger fan of the whole WWII English code breaking operation after reading Cryptonomicon by Neal Stephenson. Thus my wife and I couldn't go to London without touring (Turing would be a pun) the place where all that code breaking occurred. It should also be honored as the birth of modern computing and had one of the first digital computers (Colossus).
Well done, Richard. A silly thing to post about, but I thought the Flash-based Enigma Machine pretty cool.
