1973 SCULPTURE EXHIBITION Macquarie Callery Manuka

The 3m high version of the “Aerial sea urchin 3” erected in the court of 14 Jansz Crescent

The arms of 6mmø stainless steel rods, counterbalanced with heavy brass bars (ammonia blued) moving at random with the slightest breeze. This was the prototype of a 5m high version which Ben helped me erect at a Commonwealth Park exhibition and again at Burra.
