MGM Mirage's City Center Las Vegas opened December 16, 2009 to much hoopla and fireworks! Biscayne Group is very proud to have installed this WET design fountain in the heart of Las Vegas. Lumia is the focal point of the City Center complex. It's a laser light show combined with water jets that when in operation resemble a fourth of July fireworks display! Yours eyes can't help but be drawn to this colorful display as you drive into the circular entrance.
