Remember The Fun Theory? A campaign by Volkswagen which was conducted few months ago where people from all over were invited to submit their ideas for bringing some civic sense, improving health or environment by adding the fun element to it. The idea that created maximum buzz was the one with the Piano Stairs. 

Voting tool place out of which ten best videos were selected and the winner among them was awarded 2500 Euros.

And that is not all, the idea that was chosen as a winner has been implemented in Sweden to ensure that while driving, people stick to speed limit, not because they have to but because they can win themselves a cash price for SEK 20,000. Seven Humdred projects were submitted and below is the video for the winning entry.
