Radio Shack Robot writes "The Enigma-E is a DIY Building Kit that enables you to build your own electronic variant of the famous Enigma coding machine that was used by the German army during WWII. It works just like a real Enigma and is compatible with an M3 and M4 Enigma as well as the standard Service Machines. A message encrypted on, say, a real Enigma M4 can be read on the Enigma-E and vice versa."
"Card readers? We don't need no stinking card readers."

particularly vivid fantasy)
