I almost didn't link to this but felt the content was worth sharing despite my chagrin at the BBC for using a "Peter's" map. Anyway, the BBC provides an interesting look at urban growth around the world from 1955 to 2015. It's a pretty neat animation; use the slider under the map to change the year and see the differences. They could've used a Robinson or Winkel Tripel projection, no?!? Ugh!
