cymatics - shapes from sounds

[ramone]

This is pretty cool-maybe some of you have seen this.
You'll want to keep an eye on your volume.
Cymatics uses vibration for the effect and it might bother some if too loud.

way cool! but ehh, hows it possible that it get shapes like this..

i expected it only moved around a bit or something because of the vibrato
