Volkswagen’s Fun Theory Awards aim to incentivize socially useful behaviors by making them into games. Previously, their funds have produced a bottle recycling machine played like a video game, a trashcan that behaves like a bottomless pit, and a public staircase turned into a piano keyboard (See links, below).

Their latest award winner, Estadounidense Kevin Richardson, proposed to use a robot speed patrol camera in reverse-reinforcement mode: Record the license plates of those driving within the posted speed limit, and automatically enter them in a lottery, with cash rewards funded by speeding tickets.
