GPS coordinates can turn into beautiful things. We're inspired by how creative minds like Oakland, California resident and computer programmer Eric Fisher are taking data from open-source APIs and mapping it onto the world with interesting and thoughtful results. One of Fischer's maps shows world travel and communications recorded on Twitter: "Green is physical movement from place to place; purple is @replies from someone in one location to someone in another; combining to white where there is both. Reported trips to Null Island excluded; all other geotags trusted. Endpoints of trips are real data; routes in between are fabricated. Brightness is logarithmic. Data from the Twitter streaming API through September 1, 2011. Continent shapes from Natural Earth."
