Allows to control LED Cubes such as the LightSquared 8x8x8 3D8S commonly found on eBay as DIY kit.cu.

A LED display of 8x8 pixels is only 64 LEDs, but a LED cube in 8x8x8 is 512 LEDs, an order of magnitude harder to make! This is the reason LED cubes are only made in low resolution. Quadrum is an open-source LED-Cube framework that helps you create and upload animations to the cube (the cube can have sizes between 2x2x2 and 8x8x8). Animations can be streamed in real-time from the editor to the LED-Cube with the help of an Arduino library, alternatively get uploaded to the Arduino through the use of the editor’s code.

The Software
The software for running a static program on the 8x8x8 is pretty darn complex. But for the most part it consists of two portions:
-LED Cube Updating via Interrupt
-Main Loop LED Scheme Execution
It's simply impossible to describe everything that the software is doing (thanks to CHR from instructables for writing this software!) in this project on a single webpage so I'll just skim over what I think are the most important parts. Starting with the LED updating algorithm. In order to keep the cube up to date, we need to be constantly updating each of the 8 layers to represent changes we might have made to how things should be lit up. To do that we keep specific timing using timer interrupts and constantly updating code.
LED Cube Updating via Interrupt

Once you have the LED updating scheme working you can start having fun. Back in the main loop you can now tell the cube which LEDs to light up and where and they'll do exactly that. If you look through the code you can see some unique programs and functions that CHR has written as examples of what the 8x8x8 cube can do:

Anyway, the software is done and everyone is eager to see this thing in action so let's take a look at what it can do next in the results section, go go go!
