Forest Xylophone (2011) Forest Xylophone is a giant musical instrument built for a 2011 commercial for a cellphone with a wooden casing. The xylophone is operated by a simple wooden ball and plays Bach’s “Cantata 147”. The contraption and the music it produces are both extremely likable. It is reminiscent of The Way Things Go (1987) by Fischli and Weiss which I elected World Art Classic #463 last year. I wonder if it’s still there? Anyone?
