Interactive Hanging LED Array

Intro to Installation Art
This is not your intro to installation art... but it was my intro to installation art. What started as a conspiracy between myself and our videographer to do something big and impressive for SparkFun slowly became a PWM controlled, 72 channel, music-reactive, albatross around my neck. But, in the end, the payoff was totally worth it, and the experience of completing a whole-room project is, I would argue, an essential experience for any maker.
Let me share with you the process, plans, and source materials behind my effort to turn one of SparkFun's conference rooms into a 6x12 interactive LED matrix. That may not sound like a big matrix but when you're standing in the middle of it... it's pretty cool.
