QWOP is a game playable in Internet browsers, and iOS, by Bennett Foddy. In QWOP the player is given independent control of an athlete's upper and lower sections of their left and right legs, with the rest of the IK-controlled body following. The goal is to coordinate the button presses to get your athlete to the finish line, one hundred metres away, and this being one of the most charmingly frustrating goals seen in a videogame.
