Portrait videos are a touchy subject. As the logic goes, our eyes are side by side, not stacked on top of one another, making tall and skinny videos something subconsciously unsettling. In a very popular YouTube video two years ago, puppet comedy group Glove and Boots went so far as to call anything shot vertically "crap," while referring to frequent portrait shooters as sufferers of "vertical video syndrome."

But in Europe, a group of filmmakers have rejected that notion, and are using the format as a new medium for art. There's a festival for films made specifically for a tall and lean screen aptly named Vertical Cinema. And to make it all work, the festival's creators have come up with a special projector that stretches from floor to ceiling in locations picked specifically to overwhelm viewers with towering images.
