To show­case the natural resources that give the Touch Wood phone its unique look, an ad agency engaged Invis­ible Designs Lab’s Kenjiro Matsuo to make a giant wooden xylo­phone that stretches across a lengthy swath of forest. The Rube Gold­berg-like contrap­tion plays Bach’s Cantata 147, “Jesu, Joy of Man’s Desiring” in (seem­ingly) one take, using one wooden ball that rolls down the length of the custom-made instru­ment. The Touch Wood cell­phone makes an appear­ance at the very end.

Here’s the commer­cial.
