Weather Machine is a kinetic sculpture and columnar machine that displays a weather prediction each day at noon. Designed and constructed by Omen Design Group Inc., the approximately 30 feet (9.1 m) tall bronze sculpture was installed in 1988 in the northwest corner of Pioneer Courthouse Square in Portland, Oregon, in the United States. 2,000 people attended its dedication, which was broadcast live nationally from the Square by Today weatherman Willard Scott. The machine cost $60,000. During its daily two-minute sequence, which includes a trumpet fanfare, mist, and flashing lights, the machine displays one of three metal symbols as a prediction of the weather for the following 24-hour period: a sun for clear, sunny weather; a blue heron for drizzle and transitional weather; or a dragon and mist for rainy or stormy weather. The sculpture includes two bronze wind scoops and displays the temperature via vertical colored lights along its stem. The air quality index is also displayed by a light system below the stainless steel globe. Weather predictions are made based on information obtained by Square employees from the National Weather Service and Department of Environmental Quality. Considered a tourist attraction, Weather Machine has been called "bizarre", "eccentric", "playful", "unique", "wacky", "whimsical", "zany" and a "piece of wizardry", and has been compared to a giant scepter.
