Docomo's giant wooden xylophone delivers Rube Goldberg genius

From the deeply quirky confines of Docomo's marketing department we have what could be the most environmentally friendly Rube Goldberg promotion you've ever seen.

In a recent advertisement for its Touch Wood SH-08C model phone, a handset lovingly swathed in rich, marbled wood, Docomo hired Morihiro Harano of Drill Inc. to produce a commercial set in the woods of Japan. What gives the analog-meets-digital spot its geek cred is that it was shot all in one sitting, using a series of ramps and delicate balance, showing a tiny ball playing Docomo's theme music on what turns out to be a gigantic wooden xylophone. You can check out the beauty of its simplicity in the video below.
