Changi International Airport, Singapore
Public art installation
This is probably the most spectacular, intriguing and amazing artwork I have ever seen in an airport. (The only thing that comes close is the giant Smaug dragon in Wellington Airport.)
Two fields of a massive amount of golden drop-shaped sculptures float in the air, moving up and down in an unknown number of movements, not random, but skillfully orchestrated. The result is a flow of movement constantly creating new ephemeral wonders.
Being flabbergasted by the beauty, there is a serious risk you may forget all about your flight.
