Derek Watkins created a visualization tracking the spatial distribution of U.S. postal offices from the 18th to the 20th century. Gathering data from the USPS Postmaster Finder, with lat/long coordinates extracted from the USGS Geographic Names Information System, the results were animated using Processing. [Thanks, MR!]
