The Rainbow Serpent is a major mythological being for Aboriginal people across Australia, although the creation stories associated with it are best known from northern Australia. The Rainbow Serpent is seen as the inhabitant of permanent waterholes and is in control of life's most precious resource, water. It is the underlying Aboriginal mythology for the famous Outback "bunyip". It is the sometimes unpredictable Rainbow Serpent, who vies with the ever-reliable Sun, that replenishes the stores of water. It is known both as a benevolent protector of its people and as a malevolent punisher of law breakers. The rainbow serpent's mythology is closely linked to land, water, life, social relationships and fertility. Rainbow Serpent 3D Screensaver is an abstract homage to this ancient story, accompanied by authentic Didgeridoo music.
