RulerOf (975607) writes "Musicians recently unlocked a 600 year old mystery that had been encoded into the walls of the Rosslyn Chapel that was featured in "The Da Vinci Code." The song was carved into the walls of the chapel not using traditional notes, but in the form of geometric shapes known as cymatics, or Chladni patterns. After the entire song was decoded, it was set to traditional lyrics and recorded, and can be heard in a video featured here, at the musicians' website. The video also gives a visual representation of how the engravings match up to the cymatic patterns.
