"To bring some holiday cheer to Chicago Union Station, we partnered with Amtrak to create a magical piano that can respond in real-time to its environment," Rob Bliss Creative explained. The company is best known for elaborate, exciting stunts (like creating a 500 ft. water slide in the middle of Michigan or organizing the world's largest zombie walk), but this one is simple.
The piano plays by itself and generates some very amusing reactions from passengers (minus the guy who tells the piano, "SHUT UP!"). But if you can ignore the one Grinch in the bunch, the rest are guaranteed to put a smile on your face.
Especially the older gentleman who cuts loose and boogies with the piano.
Naturally, some commenters are crying fake, but as one replies, "It's still very entertaining"
