Pretty cool! I heard a story about a guy who was able to look at the groove patterns in a record, and then tell what classical piece it was [don't try that with an SACD, folks!]
Here's an interesting premise that I've heard postulated. While portraits were being painted, the vibrations of speech might have left a permanent pattern in the paint as it dried. Some kind of computer controlled laser scanning process might, some day, be able to read these micro-patterns. Image hearing a word or two of Washington's or Lincoln's actual voice!
