[Greg] was feeling nostalgic about the game RACE for to TI-83 graphing calculator. In the game, your car is stationary with controls to move the scrolling maze from side to side in order to avoid a crash. He set out to build a physical version of the game with a don’t-touch-the-side concept that reminds us of Operation.

The game board is a wire frame constructed from paperclips then attached to a motorized frame. The vehicle is also metal and is attached to the lens sled from a scrapped CD-ROM drive. The maze scrolls from left to right with up and down vehicle motion controlled by two arcade buttons. An Arduino controls the motors and monitors the button inputs. He has plans to add a buzzer that sounds when the metal car “crashes” in to the wire walls of the maze. We’ve embedded video of the working game after the break. For more build photos take a look at his flickr set.

[Moritz Waldemeyer], a favorite artist of ours, has a brand new project. He went wanting to design a 3D version of the game Operation. The piece he ended up with is called Keyhole Surgery. It’s essentially the laparoscopic version of operation. The player guides a metal key through the passages of a translucent block while attempting not to touch the walls. A counter on the side displays how many hits it has detected. The player with the smallest number wins. We love the modular potential of this project: the number of layers could be increased, the order could be changed, and more.
