John Boxall over at Tronixstuff posted a step by step guide on building a LED cube spectrum analyzer:

A few weeks ago I was asked about creating a musical-effect display with an RGB LED cube kit from our friends over at Freetronics, and with a little work this was certainly possible using the MSGEQ7 spectrum analyzer IC. In this project we’ll create a small add-on PCB containing the spectrum analyzer circuit and show how it can drive the RGB LED cube kit.
