Warning: this video by filmmaker Will Witte is probably going to break your brain. It's an MC Escher-esque loop of screengrabs, and, amazingly enough, none of the shots were achieved with the help of a computer.
Watch it once. Watch it twice. Watch it as many times as you can handle before your mind collapses from exhaustion. You keep wanting to figure out how Witte makes frame after frame happen. At least according to your eyes, it defies all logic. [Vimeo via booooooom via ThisIsColossal]
