Charliecube is a 4x4x4 tri-color LED Cube. But what makes it special? Other cubes use shift registers, decade counters, or other components to control all the LEDs and can cost upwards of $150. The charliecube can be run using only 16 digital pins with no extra components and costs $30 plus an arduino.

I think this is very interesting. But I’m wondering why there isn’t a video of this configuration anywhere to be found in action.
