Paper Hack

During WWII the Germans used the Enigma machine to code their radio messages… It was a very clever machine and very hard to break. A team of mathematicians led by Alan Turing finally conquered the code gaining an ear into the complex radio communications. The Enigma was top-secret for a long time, but now you can build your own with a printer. Behold the Paper Enigma Machine! Just wish I could pop in a time machine and send one to the Bletchley Park team.
