Located in Sydney’s Central Park development, Sea Mirror (or Miroir de Mer) is a permanent light artwork by French lighting artist Yann Kersalé, which is inspired by the ocean and the changing seasons. The installation is composed of 320 reflecting heliostats with 2,880 LED lights that are programmed in a rotating sequence of short ‘performances’ that reflect the Winter, Spring, Summer and Autumn seasons. Each heliostat has nine LEDs with their own program-mable URL address that light up for their show.
