Light Painting Wifi (Haunting Video)

Wireless communication channels are all around us all the time, but their variable strengths in different places create a textured, invisible part of the urban landscape. A team of Norwegian researchers, arguing that WiFi is "a fundamental part of the construction of networked cities," created the beautiful video below visualizing the strength of WiFi signals around their neighborhood in Oslo. They used a four meter pole that measured signal strength and lit up to a great or lesser degree. Then they took time delayed photos of themselves walking through the snowy streets.
