wifi painting

"WiFi uses high frequency radio to set up a data connection between a base station and device with a WiFi receiving antenna. The WiFi signal strength describes how much of the radio waves that the base station beams off that is received by the mobile device. What you see in the light-paintings is the signal strength of a WiFi network represented as a light-painted graph." Oslo School of Architecture (Yourban), via Space and Culture

pervasive information systems

"... digital activity is a layer in interface with the city. It’s not a separate virtual space, as some seem to think, but it’s augmenting our physical space. As he points out, we’re hardly going to change or destroy all these existing buildings and spaces anytime soon – urban form just doesn’t change that quickly, but the profound changes in the way cities feel and function may be in this internet-enabled informational layer." Dan Hill, City of Sound (Carlo Ratti Associati)
