That sounds pretty expensive, IMO. There would need to be one motor for each key that's isolated so only one key vibrates. And on top of it, it would be a pretty big keyboard too.

If somebody has done this before, I would love to try such a keyboard.

I'm not sure if you can get enough force from them, but maybe a piezo crystal under each key could provide localized feedback more economically and with less space requirement.
