Check out this great campaign for Volkswagen,
The Fun Theory. Seemingly very boring objects are made a whole lot more interesting by a series of experiments, captured on video to find out if making the world more fun can improve people’s behavior. The top video, Piano Stairs, has achieved over 1 million views on YouTube. My favourite, the trash can that sounds like a 50ft-deep well, will make people pick up their trash. Subtle, charming, check it out and see if it improves your day.
