Has anyone seen this Gadget Freak Case from Design News Magazine?http://www.designnews.com/article/512690-Gadget_Freak_Case_180_Tic_Tac_Cubed_Dueling_in_3D.php
Matthew Katzenstein has created a 3-D Tic Tac Toe game. It lights up with an interactive knob and is programmed to play two- and three-player versions. The game is a color-coded 3x3 RGB LED matrix.
Tic Tac Cubed is controlled by an Arduino Diecimila, a microcontroller board based on the ATmega168. Diecimila means 10,000 in Italian and was named thusly to mark the fact that more than 10,000 Arduino boards have been made. The Diecimila is the latest in a series of USB Arduino boards.
