The Fun Theory VW Piono Staircase

The Fun Theory revolves around a specific topic/item that people wouldn't normally find fun, therefore may avoid it entirely. This has been done with many things including stairs and speed cameras. However I have look further into the stairs version, this involved a set of stairs in a public area next to an escalator. The stairs where then turned into a stair piano and then on the footage it showed how more people chose to use the stairs rather than the escalator.
