Many interesting ones in this list. I like the Kryptos at the CIA headquarters. 

Here's a list of 10 unsolved cipher texts throughout history, #2 is the Beale Papers covered in the chapter, #8 is Kryptos (the background of our website). Some date back as far as 1400 BC and some are more recent like the Zodiac Killer.

We'll talk about Kryptos as some point. Elonka Dunin is perhaps the world's expert on this unsolved mystery.

Here's the paper that Robert Ward of Maryland shared with me via email last year. The stats look solid to me, although I didn't check his p-values. Let me know if you work this into any of your projects this fall!
