Watch Audio Frequencies Create Amazing Visual Patterns

It’s basically a more visually hypnotic version of the Chladni plate experiment. Basically, sand is poured onto a plate attached to a speaker. When the speaker plays a certain frequency, the sand naturally moves to areas where there is the least amount of vibration. Each frequency has its own pattern. You get to see the wonderful hidden patterns of each frequency that get more complex the higher you go. It’s beautiful. Like watching a ballet of sand. [Brusspup]
