The Fun Theory

Want more people to use the stairs – make it fun! Really like this:

I love the way it takes an every day activity which is generally boring and routine, injects some fun into it, and brightens people’s day (as well as encouraging healthy behaviour).

I wonder what other every day, mundane activities could benefit from some easily-injected fun? I guess parents do this all the time as a coping mechanism… but wouldn’t it be great to do this more in the adult world too?
