The 3D LED Cube is a really cool device that enables you to see in three dimensions, get some depth perception and has 512 LED's or 512 pixels. It is based on an arduino uno which is an Atmel AVR microcontroller on a development board with some standard interfacing pinouts that allow you to quickly assemble prototypes.

The best way to look at the hardware system is to break it up into subsystems:
By addressing the appropriate layer and column in the LED matrix, it is possible to switch a particular LED on or off or vary its intensity. For each of these sets of controls, we have an interface to the brain which is an arduino uno running an Atmel AVR microcontroller. The arduino uno is programmed via a USB port from a PC. The arduino uno brain (or AVR brain) contains standard interfacing pins which allow connection to the outside world and external devices.

- Control electronics for Columns

I'll post the code and schematic but we are working on a new one to simplify it.
You can start building the cube.
I built mine off these instructions.

BUT!!!!!
Bend the Anode leg rather than the cathode leg as he has.
eg it common anode per layer.
We had to add a transistor converter in to swap it over.
Hence the code we have if for the added convertor version of the cube.
Waiting for code und schematics. ^_^
I really think that's a good idea, just hang the lights from the ceiling and put the control box in the corner.
But this is more of a "briefly, how I did it" rather than "How you can also do it". There is virtually no info on how it could be replicated (e.g. parts list, construction detail).
Video is up!
Code and schematic coming soon.
