A designer and researcher at Oslo School of Architecture - Timo Arnall, how make things visible show us how to see the WiFi signal.
One project explores the invisible terrain of WiFi networks in urban spaces by light painting signal strength in long-exposure photographs.
Can we see this with google maps in the futures !? I think will be a great issue.
