I have stumbled upon the most delightful thing!
Have you heard of The Fun Theory? If not, then you should definitely check it out!
The website is self - explanatory, but the whole concept is basically to make things more fun to do, so that people's behaviour can be improved. I can't believe how simple yet incredibly creative this is!
My personal favorite was the staircase turned into a piano. Check and see why that was done!
