Desert Waves is a temporary art installation for the "Autumn of the Arts" festival, in the Royal Botanic Gardens. It was created by Sogetsu, a modern school of Ikebana, the Japanese art of flower arrangement. It represents giant waves, constructed from strips of bamboo. The festival runs from 4 - 25 March 2012. Today is Harmony Day, which celebrates cultural diversity in Australia each year on 21 March. This is also the United Nations International Day for the Elimination of Racial Discrimination.
