This project is heavily inspired on http://www.instructables.com/id/Led-Cube-8x8x8/. Our version of the led cube is build around a Atmega32u4 Breakout Board from Adafruit (http://www.adafruit.com/products/296).
The reason for writing our own software is that we have a different CPU and use USB instead of RS232. Also, we want to have full control from a pc/mac and run the default program only if no USB is detected.
Compiling on a Mac requires AVR Crosspack to be installed. To make sure those tools are used instead of normal gcc/as, please source the SOURCEME file which fixes the path. Also make sure that avr-gcc and avr-as are also available as gcc/as.
