Painting with light to show WiFi networks

WiFi is everywhere, floating and whirling around us somehow, but where is it really? In Immaterials: Light painting WiFi, Timo Arnall, Jørn Knutsen and Einar Sneve Martinussen use a rod of blinking lights to visualize signal strength in their college town.

“In order to study the spatial and material qualities of wireless networks, we built a WiFi measuring rod that visualises WiFi signal strength as a bar of lights. When moved through space the rod displays changes in the WiFi signal. Long-exposure photographs of the moving rod reveal cross sections of a network’s signal strength.”

The stronger the signal strength, the more lights that illuminate in that specific spot, updating as the walker/carrier moves. Then using long-exposure photographs, the lights are recorded for beautiful results. Super simple concept, yet very effective.
