Right around the time that Obama hit his 100th day in office, MIT’s senseable city lab released a series of data visualizations depicting, among other things, fluctuations in call activity recorded during Obama’s inaugural address in January. Take a look at the video below to see how call activity changed—who was calling whom, how locations shifted over time—and, perhaps of equal import, how unusually beautiful reams of otherwise dull cell phone data can become.

If you’re hooked on the visualizations and want to see more, visit the senseable city lab Obama/One People Web site or check out the site (specifically the mapping section) from MOMA’s “Design and the Elastic Mind” exhibit.
