One of the most impressive works of public art I've ever seen was in the world's largest shopping mall, the Dubai Mall. Located close to the world's tallest building (Burj Khalifi) and with views of it, are two cylindrical waterfalls that extend the full four story height (24 m) of the Mall structure.
All that flowing water seems out of place in the desert, but the sight and sound of it is beautiful and mesmerizing. To enhance the waterfalls are dozens of fiberglass figures giving the illusion of synchronized divers. This art work can be viewed from each level of the mall, and the perspective changes so take the escalator up all the floors and take it all in.
The fountains are surrounded by cafes from which you can enjoy the views while sipping on a cappuccino.
