Built for the Century 21 Exposition in Seattle in 1962, the International Fountain's original design had changing water and light patterns, with a background of classical music (though the patterns weren't specifically intended to be synched with the music.) The fountain was very large, designed as a concrete bowl around a 'moonscape' of broken limestone, at the center of which was a tiled dome studded with pointy black nozzles. The fountain was not originally designed for interaction but was redesigned in 1995 by WET to make the fountain more inviting, interactive and safe. Switching out the multicolored lights for white, WET added fog nozzles, a ring of their Shooters set into the pavers around the base of the dome, and four large SuperShooters hidden in the upper surface of the dome. The restored fountains behaves as its predecessor did for most of the day, producing changing water patterns as music plays, but it now marks each hour by bringing out other effects, like fog, and performs a choreographed show.
