Receipt Racer is a microproject by undef and Joshua Noble. It a simple game which they developed during the “Let’s feed the future workshop”, part of the OFFF Festival in Barcelona on June 8th 2011. The goal of the game is to drive a car on a race track and to avoid the obstacles. The game is self was made with openFrameworks. The design of the race track was live printed on a thermal receipt printer and the car was beamed on top of that. A very simple game very well executed!
