Arduino to flip LEDs on and off in vaguely interesting ways, Adam was showing off a 3D raycaster engine. It's like witnessing some sort of alternate history where Wolfenstein 3D came out for Atari first. Just to give you an idea of the technical challenge: half of the Arduino's memory is used up by the frame buffer alone! The game is controlled and displayed using the Video Game Shield Arduino add-on from Wayne and Layne (Adam is Wayne), which enables RCA video output and compatibility with Wii nunchucks for dual analog control. Adam actually plans to add enemies and make a full game out of his engine, just to rub it in. Need some visual proof to believe all this? Check out a video after the break. The Video Game Shield will be up for purchase on September 29 for around $22, or you can buy it at the Maker Faire this weekend.
