Light Painting with WiFi

Norway-based Timo Arnall, a designer working with interactive products and media, presents Immaterials: Light Painting WiFi, an exploration of the invisible terrain of WiFi networks in urban spaces. Arnall and his team of collaborators create “light paintings” by revealing signal strength in long-exposure photographs.

“This project explores the invisible terrain of WiFi networks in urban spaces by light painting signal strength in long-exposure photographs. A four-metre tall measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique called light-painting.”

Clearly, Arnall was not using the weak-ass WiFi in my building (courtesy of “comboplatter”), otherwise his canvasses might be blank.
