from http://davidszondy.com/futurepast/francisco-mujica.html Oct. 31, 2017 "When you first look at this future city by Francisco Mujica it looks pretty good. The building in the foreground is huge, but solid, with a nice stepped-back art deco effect going on, and the elevated walkway is a nice touch.

Then the eye begins to stray and you see the same building duplicated one after the other, marching on into the distance and you realise that you're trapped in a city that's like one of those nightmares where you keep running, but stay in the same place."
