You have to check out this video of street artist ND’A's enormous roof mural coming together. The piece must have taken all night to complete, but thanks to videographer Andrew Morton’s and director Dan Gingold’s sweet use of time lapse, you can watch the painting of the entire roof in less than two minutes. Gingold mentions it was a “frigid” night, but watching tiny little ND’A zip about the roof has its own kind of kinetic heat. Like a true artist, ND’A signs his work once the lumpy, ghostly figure is complete, and like a true neat-rooftop-timelapse artist, he signs it in bright lights. thanks to a slow exposure.
