Light Threshold

The Light Threshold was designed as a gateway to the Olympic Complex in Sydney, Australia, 2000. The work is a threshold of light that perpendicularly crosses the northern entry road and bridge to the park.

This drifting cloud of mist is animated by reflecting a yellow/gold stream of sunlight off a system of mirrors. The mirror system, gimbaled atop a sixth mast, is controlled by a heliostat computer programmed to follow the sun’s path.

By using a sequence of five 23m high masts the Threshold establishes a vertical plane that cuts across the access roadway in an open landscape. At the top of each mast is a 3m high stainless steel assembly with a series of nozzles that disperse a fine cloud of mist into the air.

At night, the mirror turns to reflect light from an artificial light source.
