Deadmau5 LED Halloween 2014 costume

My costume this year was the deadmau5 helmet but with 70 LEDs. Each one can do 256 colors so I made a rainbow effect all the way around. A microphone at the top listens to the music playing and blinks the lights to the music. I also have a headphone jack with a built in speaker, a temperature sensor with a fan when it gets too hot in there (and it damn did), and an LCD with realtime battery/temp/volume data.
