Movement in Manhattan: Mapping the Speed and Direction of Twitter Users

Inspired by the animated wind map that was posted a little while ago, professional programmer Jeff Clark has explored how people move about in a city. The result, titled Movement in Manhattan [neoformix.com], visualizes the speed and direction of Twitter users in Manhattan, New York.
The visualization is based on a large collection of geo-located tweets that were sent in a 4-hour time-window by the same users. These tweets were used as samples that together construct a vector field representing the average flow of people within a specific area. Particles, representing people, were released at locations where actual tweets were recorded and their subsequent movement was determined by the flow field.
The lines are thus traces of these moving particles, which start out blue and gradually change to red to show the direction of movement.Locations where there is little movement will have blue dots or very short blue traces. Longer traces with more red show a greater speed at that point.

The interactive map Where Does the Money Go? [stamen.com] by Stamen Design reveals the financial impact of the movements by the U.S. during 2009, on a county-to-county level. More specifically, Stamen used an open dataset containing all changes of residential address as reported to the IRS to figure out where people were moving to (blue lines), and where they originally came from (red lines).
In addition to a short description of insights (like how the migration across the country is oddly parallel to the movement of money), Stamen released an extensive documentation of their iterative design process behind this minimalistic-styled map.
This project is part of a recent challenge from Esquire magazine to 5 designers, architects, and artists, to rethink the concept of the map while depicting what is happening in the country today.
