Movie-and-pizza night usually means having to retreat to the TV in the living room, but not if you live in Hong Kong. Ad firm Ogilvy & Mather HK has built the Pizza Hut Blockbuster Box, a pizza box that turns into a projector at the drop of a hat. All you do is pluck a lens out of the protective stand, mount it in the side of the box and use your smartphone (conveniently perched on the stand) as the video source -- any video that plays on your phone suddenly becomes room-sized. There's no mention of whether or not this cardboard theater will reach other countries, but it's hard to imagine this concept being limited to one city for very long.
