The Golden Hour is a fleeting moment at dawn and dusk when the sky is aglow with a perfect light, a fragment of time during which everything is hopeful. This installation hopes to capture, preserve, and present the golden hour glow for visitors traversing the underground tunnels, a place where there is no access to sunlight. The thread responds to the corridor. As one passes through the tunnel, the tread offers a reference point for your location below ground, as the bottom edge of the thread is a level horizontal line. This installation was created on November 9, 2016, commissioned by Downtown OKC, Inc.
