Has there ever been a more beautiful artistic invention than the wind chime?

It takes a natural earth process, and turns it into music. Perfectly simplistic, no batteries or maintenance required, lasts literally forever if the hanger is solid.

Hundreds, perhaps thousands of years after the last human has perished, these little guys will still be hanging around, in every country in the world, glistening in the sunshine and playing their little tune as wayfaring critters pass by.

I just think that's so cool.
