This is the end result of my Enigma project. A (somewhat rambling and expansive) WIP can be found here.
The Enigma was a cipher used in and around WWII by the German forces. It was cracked by the hard work of Polish and British mathematicians. As a consequence of this work (and others) one of the first computers was built (Colossus).
Many thanks to all who help with feedback during the project, namely: Harleynut97, Minoribus and Rickyblender.
