The lenses and optical mechanisms used for LIGHT KEEPER were created in-house by Caitlind Brown, Wayne Garrett, and Studio North. When it comes right down to it, we were always going to have to tune the optics of LIGHT KEEPER onsite in Toronto. The distance from the lens to the concrete, the angle of the moon as it moves, the speed the rainbows cross the concrete, the specific wiring, the final programming – all of this needed to be done onsite at night, carefully tailored to the geometries and environment of the surrounding park.
With LIGHT KEEPER, we began by considering light, sight, and site, especially in relation to Lake Ontario (a stone’s throw from the public work’s final resting place). Lake Ontario is one of a handful of lakes in the world large enough to experience the pull of the moon, transpiring in tides – albeit, very small tides – a mere 1,640 km3 of lake water drawn to the gravitational pull of earth’s nearest celestial body: the moon.
