Immaterials: light painting WiFi networks

Light Painting WiFi is the creation of Timo Arnall, Jorn Knutsen, Einar Sneve Martinussen. Their work explores the invisible terrain of WiFi networks in Oslo urban spaces.

They put together a four-meter tall measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique called light-painting. By the simple action of walking down streets, they are able to pick up the thousands of WiFi signals and with the help of a long exposure camera, transform them into wall, barriers of lights.

Beyond the art aspect of this work, this technique has also a research purpose as the data collected is used to evaluate the quality of the Oslo wireless networks.
