Located at the edge of St Mark's park Mengenang (memory ) consists of 222 bamboo poles with whirling ends. Like a large wind chime these 'bird scarers' have been tuned to D Minor. Visitors are encouraged to walk through the piece, which the catalogue notes began as a reflection on the loss of life in the 2002 Bali bombings. There is one pole for every life lost. Mengenang (memory ) Mengenang (memory ) The Orme family's work is a fun piece with a serious question behind it, based on the children's querying about the lives of refugee children in detention. It consists of 100 toys placed behind bars in the tiny spaces of the honeycomb weathering rocks of the south Bondi headland.

It's a vaguely unsettling work that plays on the fear of the unknown, as the viewer wonders just what is hatching within these white nests.
