Mapping the Cloud in ‘Immaterials: Light Painting WiFi’

[From
the article
: In this video, eerie long-exposure photographs reveal the
invisible wifi networks that permeate our urban environments, making the cloud
available everywhere. …In order to study the spatial and material qualities of
wireless networks, we built a WiFi measuring rod that visualises WiFi signal
strength as a bar of lights. When moved through space the rod displays changes
in the WiFi signal. Long-exposure photographs of the moving rod reveal cross
sections of a network’s signal strength.]
