Nope, it's not a museum. This mesmerising video is of "Kinetic Rain", an installation in Terminal 1 of Singapore's Changi Airport.
Created by Berlin firm ART+COM, the weather-inspired sculpture comprises two sections, each of which has 608 raindrops — tear-shaped droplets are made of lightweight aluminium covered with copper affixed to steel ropes. They dance to a 15-minute pre-programed dance, manned by a computer-controlled machine hidden in the ceiling above. It's so hypnotising, you could stare at it for hours. Just don't miss your flight.
