Aperture Science, man. The only abandoned, robot-infested lab I'd ever want to visit more than once.
This video is part of "Other Places", a series from Ultrabrilliant detailing the unattended motion and stillness of unattended video game backdrops. It's super cool. As it happens, I've been returning to Portal 2 a bit lately, and remain astonished at just how great-looking it all is.
