"Between 1964 and 1965, Andy Warhol made approximately 500 filmed portraits of celebrities and friends. These screen tests, as they were later called, were shot at the standard speed for sound film (24 frames per second), but were projected at 16 frames per second to give them the look of a silent film. Inspired by these short films, the site
encourages members of the public to create their own 90-second screen tests via a dedicated Flickr group on the site. The films then appear on the site altered to simulate Warhol's process. What resulted is a hypnotic collection of user-generated portraits that range from the meditative to the comical and all points in between."
