Would you take the stairs over an escalator if they played musical notes with each step? You’ll have to visit Odenplan, Stockholm to ultimately make that decision, but for now, you can see them in-action.
It’s still a fun idea and apparently showed a huge increase in individuals taking the stairs.

That is really neat. I dont know why no one had thought of it before.
I really want to go try it out for myself now.
