The Xylophone of the Forest

The Hokkaido Garden Show 2015 features the Xylophone of forest created by the invisible designs lab "The creator group who changes an invisible sound into a work to see." I first wrote about this piece when it was created as an ad for the limited edition NTT DoCoMo wooden mobile phone in 2012 created by Drill. Inc. I could not find information if this is the same piece or a re-built version.

While Bach may be amused by this version of his Cantata 147, it has become a widely publicized piece with many videos - the one below being one of the better ones.
