Cymatics: Sound waves manifest light mandalas

Is there a connection between sound, vibrations and physical reality ?

Evan Grant is a creative technologist and founder of Seeper, a collective pushing the envelope of interactive arts. In this video he demonstrates the science and art of cymatics, a process for making sound-waves visible. Useful for analyzing complex sounds (like dolphin calls), it also makes complex and beautiful designs.

The example he shows from Pink Floyd's, The Wall makes me wonder if there may be a screen saver or iTunes visualizer plug-in  out there somewhere, already  ?
