My friends Bill & Amy have set up a page for their Personal Aura Device, a set of sound-reactive LED poi and clothing they’re designing and building for Burning Man this year. Seeing them in action is amazing — they have one controller with a microphone that wirelessly controls boards fitted with with extremely bright red, green and blue LEDs. The main music mode ties intensity of each color to a different frequency band in the audio, so base and drums beat in the blues, mid-tones in the greens and vocalists and guitar are followed by the red. It’s pretty hypnotic to watch, especially when they’ve got two sets of poi plus costuming all pulsing in unison to the music.
