ExtendNY takes the Manhattan grid and extends it all over the world.

Big Ben is on E. 63,709th Street and 10,896th Avenue. The Sydney Opera House is at S. 26,283rd Street and 65,946th Avenue.

An intern at Facebook plots peoples relationships using lines and it ends up looking like a map of the world (minus Russia, China, most of the middle east, etc.).

After a few minutes of rendering, the new plot appeared, and I was a bit taken aback by what I saw. The blob had turned into a surprisingly detailed map of the world. Not only were continents visible, certain international borders were apparent as well. What really struck me, though, was knowing that the lines didn’t represent coasts or rivers or political borders, but real human relationships. Each line might represent a friendship made while travelling [sic], a family member abroad, or an old college friend pulled away by the various forces of life.
