30 pixels is a game with a tangible interface. The setup of the game consists of a wooden bar with LED stripe, an electronic board integrated into the bar, an iPhone (connected through the wi-fi to the bar’s electronic board). By tilting the phone at various angles, players can balance the position of a blinking diode. The goal of the game is to keep the position of equilibrium. An idea for the game came from the video game Super Monkey Ball.
