High Water is a permanent public artwork at the Green Square Plaza in Sydney created by Lightwell. 

Installed in 2018, the artwork is a 9 metre two-sided blade with high resolution LED screens which graphically interprets local weather patterns and tidal information using integrated sensors and live data feeds.

I created the software in C++/Openframeworks using a mix of procedurally generated and hand-created watercolours. An integrated Gill GMX 600 weather sensor feeds temperature, humidity, rainfall, and wind data to the application in real time for the reactive animated visuals. Tide data is also pulled from Willy Weather for displaying low/high tide. For the sky, temperature changes the display of colours, humidity affects the size of the blooms, wind direction is represented by the movement and velocity of the animation as it tracks across the screen, and rainfall becomes water droplets that run down the screen. The sea level is shown slowly rising and falling from low tide to high tide, with its colour also reflecting the temperature throughout the year.
