Well if you ask me, I would definitely take this stairs everyday if they make it like this one.
I mean it looks cool and so much fun, I don't mind to try it..
What's the point of having technology if you don't want to use it right?
Escalators and elevators always beat stairs anyway.
But if they were to make stairs sound like piano, people will have the curiosity to try it once and even play with it just like in the video.
It will increase the numbers of people who will use stairs instead of elevator and escalator. ;)
Besides, whenever I take public transports like LRT, I always opt to use stairs instead of escalator or elevator. I don't know why but I love stairs.
But please note I don't take stairs to go to my daily classes. My classes are all at level 3 or level 4. I only take it if I'm super late, no time to wait for the elevator. ^-^
P/s: I'd love to try this piano stairs for fun, you know how much I love piano. ;)
