This essay was adapted from a TEDx talk by the same name, and has been edited and revised by the author. In an otherwise lovely photo of a crowd in Venice’s San Marco Square (see image, below), there's something curious going on if you look a little closer. Everyone's head falls roughly along the same horizon line. Now that’s odd. Everyone in the world isn’t the same height, right? This optical illusion occurs because the photographer was of average height. From the perspective of an outlier, someone of not-so-average height, the world would look far less uniform.
