Bletchley Park: A WWII juggernaut. It decrypted German Enigma (try one!) and Japanese messages on an industrial scale in huts and blocks, had an outpost in Mombasa, and built one of the first modern computers (it helped that Alan Turing was on staff). Now a diverse museum with or without a funding problem, it generated yet more intrigue in 2000 when an Enigma was stolen, and hosts a rebuilt, working Colossus that launched a cipher challenge. Beating it wasn't easy!

It's Saturday night. You're here browsing on the internet. Why not do something intellectual for a change?

A previously unbroken Enigma code has been solved by a group of hackers. After just over a month of effort, the M4 group, using distributed computing, cracked a 60 year-old German naval code. The message: "Forced to submerge during attack." There are lots of other interesting historical codes that still remain mysteries, however. Lots of Enigma goodness in an earlier post.

Flash and Java Enigma machines. And, if you're burdened with free time, an excellent text adventure in which Enigma-deciphering plays a crucial role.
