Have you ever wondered what a Wi-Fi network looks like?

Well, wonder no more. Timo Arnall, Jørn Knutsen, and Einar Sneve Martinussen of Oslo, Norway have used a four-metre home-made LED Wi-Fi strength indicator and long-exposure photography to visually map out the wireless networks of the Grünerløkka area in their home city.

The staff’s 80 LED lights blink higher and lower depending on the strength of a given wireless network, giving a look at both the effects of infrastructure on signal strength and just how widespread Wi-Fi has become in the modernized world.

While Martinussen is reportedly writing a book on the subject, the group hopes to continue their research of 3G, GSM and radio to further examine the intertwined natures of our urban existence and digital experience.
