Patterns from sound

This is cool. Someone put a metal plate on top of a speaker and spread salt on it. Sound causes the salt to move to the regions of the plate that aren't vibrating. As the frequency of the sound is increased, the pattern changes.

Warning: The sound might hurt your ears - be ready to adjust your volume quite low for comfort. Also, make sure your pets are not around while playing this video.
