Lineriders

The Lineriders car project, made by Philip Worthington and William Denniss, is a 1:43 scale toy car equipped with an array or sensors that allow it to follow lines drawn on the floor. In addition, a child can annotate the track with symbols that are understood optically by the car, telling it to alter it's driving pattern (eg. speeding up for a jump, slowing down or preparing for an oncoming obstacle or sharp turn).
