Here’s a nice example tying the most portable type of technology (most portable while still external to the body) transforming the user into a part of a whole that she can perceive as a whole. The graphics are stand-alone works of art in themselves as well.

“Using anonymous cellphone data provided by the leading cellphone operator in Austria, A1/Mobilkom, the researchers developed the Mobile Landscapes project, creating electronic maps of cellphone use in the metropolitan area of Graz, Austria, the country’s second-largest city…”For the first time ever we are able to visualize the full dynamics of a city in real time,” said project leader Carlo Ratti, an architect/engineer and head of the SENSEable City Laboratory at the Massachusetts Institute of Technology. “This opens up new possibilities for urban studies and planning. The real-time city is now real: a system that is able to continuously sense its condition and can quickly react to its criticalities,” he added.”
