The Immaterials: Light-Painting WiFi project from the Oslo School of Architecture & Design maps WiFi networks in urban spaces. Exploring this invisible terrain in long-exposure photographs, it reveals a huge light-painting across 4 meters using 80 points of light. To quote the video, "The networked city is messy, informal and seamful, and will always be a part of the complex content of city life. Light painting situates the networked city in the everyday environments in which it takes place."
