Immaterials: Light painting WiFi from Timo on Vimeo.

Have you ever wondered what your average city street would look like if we could visualize WiFi signals from routers? Well I'm sorry, but I don't have a visualization for your average city street. You're going to have to settle for Oslo, Norway. Close enough though, right? Three pretty cool guys, Timo Arnall, Jørn Knutsen and Einar Sneve Martinussen, went around Oslo with an LED light rod (which displayed nearby WiFi signal strength levels) and took some pretty impressive long-exposure pictures. From Walyou:
The rod is 4 m tall and has 80 LEDs running through its length (the more LEDs flashing, the stronger is the signal). Despite the fact that it looks like a fence on the video, actually it’s just the single rod. The amazing effect was achieved through long-exposure photography and a few weeks of walking, measuring and photographing a part of Oslo, the capital of Norway, in December 2010. The project is called “Immaterials: light painting WiFi“.
Someone should invent a similar device for visualizing smells. Sources: 1. And What If WiFi Networks Were Visible? [Walyou]
