Digital reversi board by Hanting Lu and Kai Wang from Cornell University, built as a final project:
For our final project in ECE 4760, we designed and implemented a Reversi board consisting of hardware, a microcontroller, and a touch screen. Sixty-four bicolor (red and green) LEDs were implemented as the black and white pieces of the game. Players could simply light up a LED (place a piece) by touching the touch screen in the position right above the corresponding LED. Other LEDs would be flipped automatically according to the rules of Reversi, which is programmed into the microcontroller.
