For most of us, network engineers, the IT world means anything but art. Still, it seems that out there somebody think Wifi can be use to generate art. And they did a pretty good job.
Timo Arnall, Jørn Knutsen and Einar Sneve Martinussen had this idea to explore 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.
What they achieve, you can see below:
