I found it a little boring that it could only run through a per-arranged pattern, and I was hoping to remove it's LEDs and create a programmable 3D RGB LED matrix. The main issue I am facing is finding a way to drive the matrix, and I was wondering if anybody knew of any relatively easy and inexpensive ways of doing so? I have a fair amount of electronics experience, and I am definitely interested in learning more. I also have a fair amount of coding experience for actually writing the program to drive the LEDs. So, any bright ideas noisebridge?<div>
