This picture illustrates the danger of leaving me unattended with an old ad flyer and a pencil. Below is a city which has been overtaken by pollution and chaos. A large number of the inhabitants have turned their districts into floating arcologies, and have moved to an altitude safely above the smog, leaving those remaining to collapse in on themselves. (As I'm writing this, I begin to wonder if this could be seen as a critical depiction of the rapture...) P.S. The symbols on the billboard are of a made-up alien script. They don't actually mean anything.
