"The CymaScope represents the first scientific instrument that can give us a visual image of sound and vibration - a cymatic image - helping us to understand our world and universe in ways previously hidden from view." ... you can graph change in pressure over time to get a visual image of sounds and vibrations. It is safe to say people have been doing this for a very long time. And what about the page on "sonic healing"... What a crazy site!

Like this little "fact box": http://www.cymascope.com/cyma_research/soundhealingimages/Pr..., only reference to "Prime Resonance Frequency" I could find on the web was on a few new-age sites, and apparently they have managed to find the frequency at which a cell vibrates.
