Piano Stairs

I had to share this, such a nice idea. A company selling a good feeling oppose to a brand or are they? It's a lot like the Honda musical road project, allowing the people to become more involved with what they've executed. However, do these ideas really sell cars? I would say it gets the car company's name out. The audience will be talking about it, news media, magazines, etc. so it's a great branding tool, but as far as selling a product, it's hard to say.
