Creating the Bullet-Time Effect with an iPhone and Some String in 'Centriphone' Video
The term "centripetal" refers to a force that makes a body follow a curved path, and in this case, an iPhone 6 is that body. "Centriphone" is a play on that term, as an orbiting iPhone shoots super slow-motion footage of a skier at the center of its path, as they cut their way down the side of a snowy slope. This clearly takes selfies to the next level.
