Code breakers
As someone who has always been fascinated by the role cryptology played in WWII, I found this article to be of great interest.

It seems that someone decided to harness the Internet and the power of volunteered, idling compuers, to try and track the remianing Nazi "Enigma" codes that hadn't been broken by the genius codebreakers of Bletchley Park. They've succeeded in deciphering one of them...there are more to go. Cool!
