I just discovered this project: Immaterials: Light Painting WIFI film via The Architecture Report. Immaterials: Light Painting WIFI film is produced by Timo Arnall, Jorn Knutsen, Einar Sneve Martinussen.
Arnall, Knutsen, and Martinussen explore intangible phenomena that have implications for design and effect how both products and cities are experienced. What interests me is that this film shows, as Arnall, Knutsen, and Martinussen wrote, how 'the network's behaviour depends on where it is located and how the city around it is built'. In other words, WIFI Networks are another tool, if not "layer", of/for cities. Built forms and urban landscape "can make WIFI seem spatially unpredictable." Nonetheless if WIFI networks are highly local, ubiquitous, informal and fragmented, they "make up a highly evolved, yet largely inaccessible urban infrastructure that is mainly created by its users".
