An array of Electroluminescent Wire that responds to sound. Each wire is “tuned” to a specific frequency and lights based on the magnitude of that frequency.

Several Arduino Microcontrollers with EL Shields and a Audio Input

Blue EL Wire of varying lengths proportional to the frequency they are “tuned” to.

The stringing of the EL wire should be artistic and geometric. An observer should be able to view the entire device at once.
