3D LED Tic Tac Toe Answered

I found this cool 3d LED Tic Tac Toe game on Make this morning.

A 3x3x3 LED matrix connected to an Arduino allows you to play 2 or 3 player 3D Tic Tac Toe as red, green or blue.

While the box isn't of the best quality it's a pretty neat idea and seems to work really well!

Looks good! I'd love to know how to make it.
