This is what the Internet looks like

A team of designers and researchers of the Oslo school of architecture and design last week launched a new film in which they visualize wireless networks in Grünerløkka, Oslo. The film "Immaterials: Light painting WiFi” is in a few days viewed by over 100 000 online and has gained wide international attention.

The film "Immaterials: Light painting WiFi" is made by Einar Sneve Martinussen, Jørn Knutsen and Timo Arnall from AHO's Institute of Design. All three are currently working on their PhD thesis in interaction design, related to various research projects at the institute. The film is part of the research project YOUrban, dealing with the intersection between design, technology and urban life.

- In everyday life we are surrounded by invisible technological phenomena, which to a greater or lesser extent, affects the way we use and experience our surroundings. We want to uncover some of these phenomena and show how they are part of the cities and the places we live in", says Einar Sneve Martinussen.

The project explores the invisible terrain for wireless networks in urban space through measuring the signal strength with LED lights, "captured" by long exposure photographs. A four meter long measuring rod with 80 points of light reveals the meeting points between different WiFi networks using a photographic technique called "light painting”. The technique was developed in 2009 for the film "Immaterials: the Ghost in the Field", which shows the invisible fields surrounding RFID readers.
