Spectra (2004) is a series of installations created by the new media artist Ryoji Ikeda. It is produced using an array of xenon search lights that is accompanied by a sound system of a mathematically derived score. His work has been installed in multiple locations including London, Tasmania, and JFK International Airport, and the number of lights and scales vary depending on the sites. Its white lights and ultra-high frequency sound component present the viewers with an ethereal experience as they walk through the field of light. The scale of the work is one of its most noteworthy features; the xenon lights shoot straight up into the sky, allowing a broad range of audiences to see the work. I would love to experience the work’s symphony of ultra pure sine sound waves; its sound is just as beautiful and celestial as the captivating visuals.
