How to get more people to walk the stair?

I just clicked this link and really really found this idea is so lovely that almost people will fall in love with. Basically, this idea offers me two very nice points of view. First of all, of course, it's about the music. The person or group who came up with this idea was designning the stair as a keyboard. So, the sound of music will be produced by stepping on them and you can also make it a beautiful melody unless you get more friends to do with that. Second, this reason can be very very very subjective because the place where you can find in this video is Stockholm where that captial of Sweden where some of my best pals live.

Anyway, why don't we try to make it here as well? But as long as there're not " too many" people to step on them "too much." That way, stair can be vivid!!!
