'Magical piano' surprises commuters

Rob Bliss Creative teamed up with Amtrak to bring a little magic to Chicago's Union Station. They set up and filmed a 'magical piano' that played by itself and appeared to react to its surroundings.

For example, when a young girl sat down to play 'Chopsticks,' the piano joined her in a duet. Musician Andrew Blendermann was watching and listening from a remote control room where he controlled the piano.

Some of the people featured in the video were actors, but the video was still very magical.
