This isn’t your traditional post about a startup per se, but a post about a cool experiment some Norwegians came up with. They wanted to uncover the numerous WiFi networks in the city and make them visible. Cities are continuously experienced in different ways as the amount of devices relying on WiFi networks increases. This experiment is part of YOUrban, a broader research project from the Oslo School of Architecture and Design.

They created the film below with the help of a simple wooden rod bundled together with some led lights and WiFi network detectors. This rod was then moved slowly and recorded by a camera with long exposure. As the signal got stronger, the rod showed more lights and when the signal was weaker fewer lights were shown. This project was made by Timo Arnall, Jørn Knutsen, Einar Sneve Martinussen and it’s a fascinating look into the invisible side of our cities that so many technology startups depend on.
