Here’s a neat experiment/art project: a grand piano that “plays” passing clouds.
American artist David Brown set up this special piano to observe the sky in 88 different segments (for the 88 keys, geddit?). The clouds that pass through those 88 regions are then analyzed for the speed at which they’re moving across the sky, their size and density. That data is then transferred to the keys corresponding to that region of the sky. Here’s how it works according to The Daily Mail.
