"Dancing Colors," is a striking photo series by Zurich, Switzerland-based artist Fabian Oefner that visualizes sound through capturing the motion it creates.
Oefner placed tiny colored crystals on top of a membrane above a loud speaker. When he turned on the speaker, the vibration of the music would cause the crystals to jump, thus "making sound waves visible."
Using high-speed photography, Oefner caught the crystals in motion, creating waves, splashes, and explosions of color. The results are fantastic!
