A nicely written quote about invisible geographies, hybrid physical/virtual spaces, and urban data streams from the City of Sound blog:
"The way the street feels may soon be defined by what cannot be seen with the naked eye.
Imagine film of a normal street right now, a relatively busy crossroads at 9AM taken from a vantage point high above the street, looking down at an angle as if from a CCTV camera. We can see several buildings, a dozen cars, and quite a few people, pavements dotted with street furniture.
Freeze the frame, and scrub the film backwards and forwards a little, observing the physical activity on the street. But what can’t we see?
We can’t see how the street is immersed in a twitching, pulsing cloud of data. This is over and above the well-established electromagnetic radiation, crackles of static, radio waves conveying radio and television broadcasts in digital and analogue forms, police voice traffic. This is a new kind of data, collective and individual, aggregated and discrete, open and closed, constantly logging impossibly detailed patterns of behaviour. The behaviour of the street."
