Wifi signals visualized as a light painting

Via Geekbeat.tv

We all know that countless radio signals are coursing around and through us in our increasingly wireless world. But it’s easy to forget about this invisible layer…unless you have a way to visualize it. One group of artists decided to do just that. By taking a four meter rod fashioned with 80 lights, they created a “light painting” that reveals the pattern of wifi signals around various urban structures in the Grünerløkka area in Oslo. The bar lights up proportionate to the strength of the wifi signal. The result is a semi-transparent three-dimensional graph of light which is both beautiful and fascinating.
