Must-see: Pizza Hut's new box becomes movie projector for smartphones

Movies and pizza: They're clearly a perfect pair, right? Well, Pizza Hut is turning its disposable cardboard boxes into something you may want to keep – even after the pie is gone.

It's called the "Blockbuster Box." Developed by advertising agency Ogilvy Hong Kong, the box comes with a perforated, pop-out hole on the side of the box and a plastic pizza table that also serves as a projector lens. All you do is slip the plastic lens into the hole, place your smartphone inside and your movies on the phone's display are projected onto a wall, giving you that real movie theater experience.
