So this video is a little off-topic for my usual posts, but it was too fantastic not to share. Basically, there's a giant xylophone made from thousands of bits of wood... set up in a forest. By rolling a ball down a continuous downhill track, the xylophone plays Bach’s Cantata 147, Jesu, Joy of Man’s Desiring. The whole thing is actually a commercial for some limited edition phone, but that aside, it's a crazy cool piece of art. Credit goes to Invisible Designs Lab’s Kenjiro Matsuo.
