This is a simple spectrum analyzer on an 8x8 red/green LED Matrix. An Atmel ATMEGA32 microcontroller talks to a laptop running an mp3 player called XMMS on Linux. XMMS does a fast-fourier transform and sends the computed values to the microcontroller.
Code is available on my website at http://separaterealities.com/projects/spectrum_analyzer
