Forest Xylophone

Back in 2011 the Japanese telecom company Docomo created a large forest xylophone to promote the then new Touch Wood SH-08C cell phone. A wooden ball rolled down the steps of the instrument playing Bach's Cantata 147 as it progressed to the bottom.

The xylophone was reintroduced at the 2015 Hokkaido Garden Show where visitors could purchase a ball from a vending machine to play the instruments tune.
