The installation talks about ecological problems in the ocean, in two different locations in Australia. The installation consists of ‘Urchin Corals’, 3d-printed from the shells of the purple sea urchin (Heliocidaris erythrogramma) and the Black sea urchin (Centrostephanus rodgersii) blended with biopolymers. The installation also includes an underwater film by Tom Park.

In Port Phillip Bay and in many other places in the world, due to anthropogenic reasons, sea urchins are exploding in numbers. They eat their way through the seaweed habitats until only an underwater desert remains. In many parts of PPB this has already happened.

The installation consists of corals as the work on the sea urchin shell material has led to further research on materials that we are currently testing for coral restoration purposes.

More about the installation here soon!
