I am working on a book of LED Cube Projects

I have been working on a book of LED Cube Projects.  It might end up being two books one for the Arduino and one for the Raspberry Pi.  So far I have built a 4x4x5 LED cube and a 8x8x8 LED cube. Coming up next is a Color Cube likely 6x6x6 in size.

Here is a picture of the 8x8x8 LED Cube from above.

This first picture is of a 3D slice cutting through the cube.

This next video is of "falling rain"

Here is a picture of it running with a Raspberry Pi.
