Create your own 8x8x8 Led Cube 3-dimensional LED display!
This Instructable is the most comprehensive step-by-step guide to build an 8x8x8 Led Cube ever published on the intertubes. It will teach you everything from theory of operation, how to build the cube, to the inner workings of the software. I will take you through the software step by step, both the low level drivers/routines and how to create awesome animations.
About halfway through the Instructable, you will actually have a fully functional LED cube.
