Earth v Sky (opened by the Lord Mayor of Sydney 24th April 2012)

commissioned by the City of Sydney

site: Bicentennial Park, Glebe, Sydney Harbour

This environmental art installation, centred on Glebe Point’s magnificent Moreton Bay fig trees, explores the relationship between earth and sky through light and colour.

Lights bathe the trees in their own ever changing ‘opposite twilight’ for just over an hour each day after sunset. To achieve this, a world first custom-built colour-sensitive system continuously samples, then inverts, the colour of the evening sky, rendering the trees light-articulate.

Power to this installation is sustainably offset by the City of Sydney’s first wind turbine. As the earth seeks to balance the sky through colour opposition, the turbine seeks to balance the electrical power used that makes this opposition possible.
