The fun theory, an initiative by Volkswagen "is dedicated to the thought that something as simple as fun is the easiest way to change people's behaviour for the better. Be it for yourself, for the environment, or something entirely different, the only thing that matters is that it's change for the better."

There are two videos posted: in one, a subway staircase, often neglected in favor of the escalator, is turned into a musical keyboard and attracts more use.

In practice, I wonder if the crowds during rush hour would find the sounds more stressful than fun, but it would be easy to implement something to limit the instrument's output at that time...

More fun! I'm for it!
