Tagged “the Warhol of Web TV,” online entrepreneur Josh Harris used the wealth he accumulated as founder of the webcasting site Pseudo.com to stage forward-looking and ultimately nightmarish human experiments in digital media. For “Quiet” he recruited a hundred New York scenesters to spend a month whooping it up in a bunker whose rows of front-facing bedchambers, each equipped with a 24-hour webcam, were inspired by photos from Nazi concentration camps. For WeLiveinPublic.com he installed webcams in every room of his apartment (as well as the toilet bowl) and streamed online everything that happened to him (like losing his fortune when the dot-com bubble burst and his live-in girlfriend when she tired of being a guinea pig). Documentary maker Ondi Timoner (Dig!) worked for Harris on “Quiet,” and here she uses her access to create a frightening portrait of a man whose technological genius fails to compensate for his gaping emotional deficits: the first shot is a video message in which he blithely bids goodbye to his terminally ill mother. 90 min.
