There was a very interesting article in the Chicago Tribune today about a message, written in code, that arrived at Fermilab in Batavia, Illinois. The message arrived in a plain envelope, addressed merely to "Fermilab." In hopes of cracking the code, they posted the letter in May on their Internet Blog. They've figured out part of it, but not the second message. They're pretty sure it's from an insider.

I'm thinking that mathematically inclined linguists might be able to decipher it. How about it, Wordcrafters?
