Now to the art of running; Kiwi Peter Mitchell's marked a milestone birthday by running around the world without leaving Melbourne, and he's created a masterpiece along the way. Using GPS he mapped the outline of a world map; he's then run the perimetre of the image, the outline of the route is then saved to one of those apps that maps your run. In this case, a stunning map of the world; where most mere mortals have daily GPS jogging routes that look like a mad ant or a zig zagging drunk. Peter Mitchell has also created images of a koala, a guitar and a footballer in action, he spoke to Lisa Owen.
