Have you wondered why video game characters bear precious little resemblance to the people you see on the street? PBS has. Its latest Game/Show episode dives into the reasons why bodies in games are so exaggerated, and finds that it's largely about the psychological associations you make with geometry. Circular shapes tend to communicate liveliness, innocence and stereotypical femininity, while squares and triangles often suggest balance, hardness and (historically masculine) strength. They're meant as a shorthand that conveys what a character is about before you even start playing, such as a tough-as-nails Gears of War soldier or a friendly mascot like Mario.
