Wireless networks in the physical world
For the most part, you go about your day-to-day with little knowledge of all the bits and networks you walk past or intersect with. Designer Timo Arnall visualizes these wireless networks of WiFi, bluetooth, etc. in the physical world (video below). It's a simple idea. As we move through the landscapes, white dashed circles move around buildings with WiFi and people carrying mobile gadgets.
Here's the artsy fartsy description:
Utopian and radical architects in the 1960s predicted that cities in the future would not only be made of brick and mortar, but also defined by bits and flows of information. The urban dweller would become a nomad who inhabits a space in constant flux, mutating in real time. Their vision has taken on new meaning in an age when information networks rule over many of the city's functions, and define our experiences as much as the physical infrastructures, while mobile technologies transform our sense of time and of space.
I'm not sure if these are real wireless networks detected with a sensor or simply made up. I'm going to assume the former. It's much cooler that way.
