As Engadget says:

“Ready to have your gray matter softly stroked? Perhaps you should take a trip to BMW’s recently opened museum in Munich, where a kinetic sculpture comprising 714 metallic balls suspended in air will soothe your weary mind. It’s one of those things that’s better seen than described, but if you can imagine a wave of undulating orbs that appear to weightlessly float, you’ll start to get the idea. Can’t afford the flight? Check out the video — which features some serious easy listening jams — after the break and see the installation in action.”

The sculpture is awesome isn’t it? Have a look at BMW Museum website and see the video here
