What if the horizon bent the other way?

An interesting map of Manhattan from Schulze and Webb – looks like some sort of inverse cylindrical projection. [Update 12:56 PM: On closer inspection, the buildings obey a different projection scheme than the ground!] In any case, it makes you think about the reasoning that goes into making maps, which is something I try to teach in physical geography. Thanks to Ethan for the tip.
