Touch Fighter is the first official game for the iPhone, developed by Apple engineers over the course of two weeks. It uses Open GL. Players fly a Star Wars X-Fighter through space, steering by using the iPhone like a pretend control wheel, with both hands on the side. Drop your left hand to turn left, like you're driving a car. The accelerometer opens up all kinds of development possibilities, a necessity since there are no physical buttons on the iPhone.
