Heath Young shared his Blue Wall Defender Arduino Game in the Adafruit Forums:
I have created a game using an Arduino Mega 2560 and 6 x 12mm Diffused Thin Digital RGB LED Pixels (Strand of 25) – WS2801.
Game Title: The Blue Wall Defender
Description: Defend your blue wall against the invading Red and Green dots that are trying to destroy your wall. The wall has 6 hit points and each enemy takes 1 off. The enemy’s can not harm you only the wall. There are three buttons the middle one(Number 2) will start the game and shoot, the other two will move you up and down.
Screen Size: x-15 pixels X y-10 Pixels
Screen Setup: I have 3 screens of 50 Leds combined into one screen.

12mm Diffused Thin Digital RGB LED Pixels (Strand of 25): RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a ‘dot’ of silicone. The dots are weatherproof and rugged. There are four flanges molded in so that you can ‘push’ them into a 12mm drill hole in any material up to 1.5mm/0.06″ thick. They’re typically used to make outdoor signs. We also have flat-backed pixels that are essentially the same, but are not as long and thin. (read more)
