What, you mean you boffins don't know what this thing is? It's obviously a cloud harp, duh, and it translates the
movements of clouds into musical notes by firing infrared beams into the sky. Just like the way a CD player's laser
reads the pits in a disc and converts them into sounds, this, um, thing reads variations in the texture and density of
passing clouds to produce what we're sure is a kind of cacaphony that would make Autechre proud.
