But, there are actually two other videos up on their site that, while not as music-tastic, are equally enjoyable to watch.
I absolutely love the whole philosophy behind it - make something fun and people will do it. On their website, thefuntheory.com, it says:
This site 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 for something entirely different, the only thing that matters is that it’s change for the better.
Change the world by having fun? That's a bandwagon I'll gladly jump on!
P.S. I'm planning on moving to Sweden if only to take the stairs, throw out rubbish and recycle my glass bottles.
