The Fun Theory

The researchers I worked with at MIT had been working on a project to get more people to use the stairs coming out of the subways. At the time I was working with them they were trying to develop health messages to put on signs near the escalators (to guilt people into using the stairs). I'm not sure what eventually happened to that project, but this makes way more sense. I mean really, what do they know at MIT?

My only question is--how long until the novelty wears off? Once it loses that, then I think you're back at square one. Here is the link to the website which has a couple other ideas/videos.
