Check out the unofficial list of unsolved codes and ciphers, including the Beale Ciphers which might have been the inspiration for that utterly uninspiring movie National Treasure.  Included in the list are some ancient scripts which have defied translation for nearly 4000 years!  Don’t forget about the coded messages left behind by the Zodiac Killer – not all of these have been broken and the killer has never been caught.
