The Festival Centre Plaza also serves as host to an outdoor collection of sculpture, including the prominent stainless steel Environmental Sculpture (also known as Tetrahedra), by Bert Flugelman.
The best-known is the 4m tall The Spheres by Bert Flugelman; two large stainless steel spheres with a diameter of 2.15 metres balanced one on top of the other.
