This amazing video is an ad for the Sharp’s SH-08C handset. Pretty cool how they built a long stepped wooden ramp, down which a wooden ball rolls and strikes a wooden bar to produce each note. The video goes on for about 2 minutes, during which the impacts play some of the 10th movement of Bach’s Herz und Mund und Tat und Leben.
The video was uploaded one day before the earthquake and tsunami.
