Making sounds visible: Sound vibrations transform colorful sand patterns

Japanese performance artist Kenichi Kanazawa taps a rubber mallet on a steel table to make sound vibrations that create beautiful transforming sand patterns. Using a scientific sound-visualizing process called Cymatics, he is able to manipulate the complex sand shapes by making frequencies visible through these vibrations: the higher the frequency, the more complex the design.

Previously: More Chladni patterns and some Oobleck, just for kicks.
