“The Fun Theory” was initiated by Volkswagen in an effort to alter people’s behavior for the better by taking the monotonous and making it extraordinary.

They then transformed a normal set of stairs into a functional piano and watched as a reported 66% of passersby chose the “fun” route over the nearby escalators.
