Longest Neon Sculpture in the World
Have you passed along the neon walkway at Terminal 1 of Chicago's O'Hare International Airport? This 744 foot neon sculpture is reportedly the longest neon sculpture in the world. The piece is called the "Sky's the Limit" by California artist Micheal Hayden with music by William Kraft and was installed between United passenger concourses B and C in 1987.
The sculpture is composed of composed of 466 colored neon tubes of 14 foot and 9 foot lengths. They run the entire length of the ceiling above the moving walkways. The first and last sections of the three-section sculpture begin with white neon tubes. The center section starts with indigo and proceeds through the spectrum from shades of blue to green to yellow to orange to bright red. The light sculpture is controlled by three computers that generate patterns of light pulses that never repeats themselves.
