A giant, moving water colour artwork overlooks Green Square plaza. Its 9-metre LED screen, which displays vibrant blues, reds and greens, was created by a Redfern-based artists Indigo Hanlee and Michael Hill of Lightwell. But the entity responsible for animating the artwork is not human.

The artwork High Water takes real-time weather for Green Square and Sydney ports and displays this in fluid pigments. The weather, temperature and tides determine this ever-changing display.

The artwork is made with hand-painted water colours and a digital art technique that continuously generates images. The constantly changing image will, over time, form a visual archive of our changing climate.

The artists hope Green Square residents enjoy watching High Water through the seasons. They say: “Green Square is a changing neighbourhood, so there are some great parallels between the changing patterns of the climate and the area itself.”

High Water comes with a responsive web app to help you interpret the weather data it displays.
