But really fun to watch!

1. Oh come on. It's actually fun.

Some of the patterns are quite lovely, and let us know that there is more beauty going on in nature than we can perceive.

2. That is so badass!

Thanks!

3. Oh, wow.

Is that for real? That's amazing, seriously.

6. Way cool!

But I got fined by the cats for playing unauthorized sounds. :P

8. Ha!

Glad folks have enjoyed it.

These are just the sorts of things that loudspeaker manufacturers try to remove from each flat surface on a cabinet. And musical instrument makers try to enhance.

Extremely interesting stuff!

7. That was seriously cool!

11. Musicians unlock mystery melody in chapel

Thomas Mitchell, a 75-year-old musician and ex-Royal Air Force code breaker, and his composer and pianist son Stuart, described the piece as "frozen music."

"The music has been frozen in time by symbolism," Mitchell said on his Web site www.tjmitchell.com/stuart/rosslyn.html, which details the 27-year project to crack the chapel's code.

"It was only a matter of time before the symbolism began to thaw out and begin to make sense to scientific and musical perception."

The 15th Century Rosslyn Chapel, about seven miles south of the Scottish capital Edinburgh, featured in the last part of Dan Brown's "The Da Vinci Code" -- one of the most successful novels of all time which has been turned into a Hollywood film.

Stuart Mitchell said he and his father were intrigued by 13 intricately carved angel musicians on the arches of the chapel and by 213 carved cubes depicting geometric-type patterns.

Years of research led the Mitchells to an ancient musical system called cymatics, or Chladni patterns, which are formed by sound waves at specific pitches.

The two men matched each of the patterns on the carved cubes to a Chladni pitch, and were able finally to unlock the melody.

(PS: Thanks for the lovely visual demonstration).

14. Now -that's- interesting code work!

Thank you very much for sharing that. This is the sort of real-life mystery that overshadows fiction for me.
