Inspired by movies like "They Live", "The Spiderwick Chronicles" and countless spy films, I wanted to create a means of displaying information in public, that only a select few could see. To the unaided eye, the mosaic of tinted film squares seems uniform and holds no particular meaning. But when viewed though a polarized filer (or a pair of polarized sunglasses), the concealed message becomes clear.
