Sound is something of an ephemeral phenomenon, existing in the moment that vibrations travel through the air. Those vibrations also exhibit distinct patterns, depending on frequency, which can be visualized by scattering a fine dust over a vibrating plate. This was the inspiration for Resonantia, an album whose…
Nigel Stanford's song Cymatics is named for the study of visible sound vibrations, and we see sound made visible in this music video. In fact, this video is a treasure trove of science, with ferrofluid, Chladni plates, Tesla coils, and a fiery Ruben's tube.
This one-minute film manages to be visually engrossing with an extremely limited medium. Cymatics consists simply of lycopodium powder dancing on a surface vibrating at 50 Hz.
This video looks absolutely computer-generated, as though it were made by some super-advanced particle engine. But this is actual, real-world video footage, showing a fine power called Lycopodium reacting to vibrations from speakers placed directly below it. Amazing!
