New York Talk Exchange project

hi, I just came across details on a new exhibition in New York, organised by Carlo Ratti and colleages. Described as follows:

"New York Talk Exchange illustrates the global exchange of information in real time by visualizing volumes of long distance telephone and IP (Internet Protocol) data flowing between New York and cities around the world."

The underlying concept of this project reminds me of Jean Gottman's classic work in the late 1950s trying to map out telephone call flows. Some of this was published in Megalopolis: The Urbanized Northeastern Seaboard of the United States (1961), with thematic maps like the one below.
