‘Surface’ Interactive Light Sculpture (Perth, Australia)

“Surface” is an interactive light sculpture by Geoffrey Drake-Brockman. It is a 3D LED matrix – one of the largest in the world at 10m long and with over 16,000 individually controlled pixels. Surface is permanently installed at the Perth Children’s Hospital. It behaves like an inverted pond of water,.. each time a pedestrian walks underneath it they “throw a stone” into it, causing ripples to fan out across its virtual water surface.
