A short video clip of the "Halo" water feature inside the Crystals mall in Las Vegas. A CityCenter press release describes it thusly:

Halo materializes as a series of water vortices held captive within clear cylinders that thrust up through the floor. Sloped, as though about to fall, the swirling water appears caught in constant struggle to right itself with its inherent sense of verticality. These swirls of color serve as a main focal point of the atrium. In between stops at Louis Vuitton and Gucci, guests and visitors are free to walk through and touch or embrace this maze of spinning water while staying completely dry. WET’s elemental features at CityCenter set the spirit for the sophisticated experience that visitors to this unprecedented destination will enjoy.

WET Design, the firm behind all of the CityCenter water widgets, has this to say about it:

WET's cutting-edge creations help to reveal a world of fascination and wonder at every turn at CityCenter in Las Vegas. The water designs play an integral role in producing an immediate feeling of elegance and surprise throughout the grounds. Crystals, the stunning retail and entertainment district, designed by architects Studio Daniel Libeskind and Rockwell Group, houses Glacia and Halo, two cutting-edge features that exist in pure harmony with one another. The unexpected nature of Halo's twisting water vortices, tipped as though about to fall, enlivens Crystals' shopping experience and presents a sense of mystique for guests wandering among the lavish shops. Visitors are free to stroll through, touching or embracing this maze of spinning water, all the while staying completely dry.
