Each year, we’re continually amazed at the pop-up architecture that rises in Nevada’s Black Rock Desert for Burning Man only to be destroyed in one grand flash of fire. What’s equally awe-inspiring is the pop-up city that forms around the festival. We just came across this time-lapse video of the rise and fall of the city of Burning Man, which shows how the urban form, like the installations, slowly builds before igniting in the night and fading away. Set against the black of the desert night, the video shows how active and dynamic the site really is when the sun goes down. The festival comes alive with the darting about of lights around fixed centers of music and art. At the end, the calm of an abandoned desert returns for another year. [h/t Lost at E Minor.]
