FROG Zero

A custom solar telescope on the roof tracks the sun and beams daylight through a series of mirrors to light a 240 foot fiber optic sculpture. The luminous sculpture provides a connection to the sky for those deep in the enclosed stairwell. Both sunlight and a connection to changing sky conditions are present as the sculpture continually varies in brightness and color, giving cues about clear or cloudy skies and also the time of day. A real time optical solar image of the sun is projected on the ceiling allowing the viewer the unusual opportunity to look into the sun.
