This is one of the coolest art installations I've ever seen. It looks like some alien technology that was left behind in the middle of nowhere! There's not much information on it but from here's what I've gathered so far: The Singing Ringing Tree is designed by architects Mike Tonkin and Anna Liu. It's 3 meters tall made of steel pipes of varying lengths. The hollow steel pipes allow wind to pass through them creating this eerie but beautiful sound.
