A VIDEO

Cool animation mapping the online social activity of New York City by Christian Marc Schmidt.  It’s kind of like watching a PET scan of Manhattan.

(Note that, if you watch closely, you’ll probably see a few terms zip by in captured Twitter messages that probably aren’t appropriate for K-12 classroom use, so “teacher guidance suggested.”)

By revealing the social networks present within the urban environment, Invisible Cities describes a new kind of city — a city of the mind. It displays geocoded activity from online services such as Twitter and Flickr, both in real-time and in aggregate. Real-time activity is represented as individual nodes that appear whenever a message or images is posted. Aggregate activity is reflected in the underlying terrain: over time, the landscape warps as data is acccrued, creating hills and valleys representing areas with high and low densities of data.
