Kouichi Okamoto has created this art/music project that is just fantastic. It’s 504 musical boxes, all attached to a table via wire, with each musical box playing just a single note. The knobs on the table control the speed at which each of the music boxes play.
I’m sure that it’s great fun to play, but imagine what it must sound like in real life from a spatial perspective with 504 music boxes playing spread out over such a large area. Wow.
