Strawberries and cream, Bonnie and Clyde, Gin and Tonic, beer and pizza and of course pizza and movies. Pizza Hut has made their own Smartphone projector from their pizza boxes. Printed on the side of the box is a QR code to an app with the movies to watch. Now that’s upcycling! The smartphone projector is a relatively simple concept that works off the camera obscura principle which projects light outward from a source.. You pretty much just need an old box of sorts and a biconvex lens
