If you look upwards at the apex of the shade struc­ture you might see, depend­ing on the time of day, the Arrernte names of the three ances­tral cater­pil­lars – Ayeperenye, Ntyarlke and Utnerren­gatye – illu­mi­nat­ed by the sun on the rust­ed steel sup­port beams. This art­work was com­mis­sioned by Alice Springs Town Council.
