15x15 is a website that plays on Andy Warhol's theory that 'In the future, everyone will be world-famous for 15 minutes'. The site constantly shows 15 boxes, each playing a 15 second video clip captured using mobile phones. The videos can be of any content, as long as it is not offensive. The variety of the clips is pretty entertaining. Clips can be submitted by anyone by uploading them from your computer or sending them directly from your phone using MMS.
