Intermission: Light Paintings Illuminate Wi-Fi Waves

Everywhere we go, invisible Wi-Fi signals permeate the landscape. Using a four-meter rod of lights and long-exposure photography, a group of Norwegians brought those unseen forces to life.

Affiliates of YOUrban, a research project at the Oslo School of Architecture and Design, designed the rod with dozens of small bulbs that flash depending on the strength of the Wi-Fi signal at any particular spot. As the lights travel through the city, a hidden picture of airborne information reveals itself, like technological ghosts in the night.
