Sound Architecture IV by Ronald van der Meijs is a different sort of “carol of the bells”. It’s made up of 5,000 bicycle bells installed to sway and interact like reeds. When the wind blows they brush together and make chiming sounds.
Astonishingly beautiful real-time visualization of wind in the US. Have you seen it? If not, you really need to click through and see this baby in action.
(Thanks to the lovely Posey Gruener for the heads-up.)
