This is pretty cool:

A Scottish church featured in The Da Vinci Code is embroiled in a fresh mystery of secret codes and heretical knowledge - but this one could be more than mere fiction.

An ex-RAF codebreaker and his composer son say they have deciphered a musical score hidden for nearly 600 years in the elaborate carvings on the walls of Rosslyn Chapel.
...
"I was obsessed by these symbols. I was convinced they meant something." Using codebreaking skills learned during the Korean War and his knowledge of classical music, Thomas Mitchell finally realised that the cubes depicted patterns made by sound waves.

You can listen to an interpretation of the music here.  I listened to it last night, and it is quite beautiful.  Start your morning with some inspiration.
