Born in 1962 in Yuendumu, Ursula Hudson Napangardi lives in Nyirripi, 150 km west of Yuendumu. Ursula has been painting in the Yuendumu artists' community since 1993. Her main themes are her father's Yuparli Jukurrpa (Bush Banana Dreaming), her aunt's Pikilyi Jukurrpa (Vaughan Springs Dreaming) and her mother's Ngapa Jukurrpa (Water Dreaming). These dreams have been passed down from generation to generation for millennia and relate directly to the land, its characteristics and the plants and animals that inhabit it. 

Ursula uses a vast palette of colors to develop a modern interpretation of her traditional culture. In her works, Ursula Hudson presents her version of the Dream of Pikilyi, a sacred site with a waterhole and stream not far from Yuendumu. Legend has it that a pair of Rainbow Serpents used to live there. Women would come to remove the lice attached to the bodies of the two mythical beings, in exchange for the right to take water from the stream. The Aborigines still celebrate ceremonies in this place, where the spirit of the two snakes still resides. This Dreaming belongs to several family groups and illustrates the complexity of desert social structures.

These are based on a kinship system that assigns each member of society a place in one of eight possible kinship groups. These groups are arranged in pairs, with each pair jointly ensuring the preservation of the art's themes: land, ceremonies and dreams. This painting tells a story that belongs to two paired male groups, the Japangardi and Japanangka, and two paired female groups, the Napanangka and Napangardi, i.e. the artist's clan. On the canvas, the wavy lines represent the water flowing into the river, and the concentric circles, the sacred site.
