Atlanta
Centennial Olympic Park was built for the 1996 Summer Olympic Games, which were held in Atlanta. The centerpiece of the park is the Fountain of Rings. At various points during the day, the Fountain of Rings is taken over by a computer and randomly attacks passersby with high-powered jet of water. Hee! Actually, the computer is programmed to synchronize the lights and water jets with music. It's pretty cool.
