WiFi visualized

This film made by Timo Arnall, Jørn Knutsen and Einar Sneve Martinussen uses light to map the existence of wireless networks around the city of Oslo. They constructed a measuring pod that creates a real time graph of the wifi intensity. By turning the light on and off and documenting it with long exposure photographs, YOUrban have assembled impressive images of a normally invisible side of the urban landscape.
