Indigenous Arts, culture and design

I know very little about Indigenous arts, culture and design, but what I have been exposed to, so far is very exciting and richly layered. What is most astonishing to me, is the immense time frame that exists in Australian Aboriginal culture and I look forward to learning more.
The concept of 'Dreaming' in Aboriginal culture is something I hear frequently. This is what 'The Oxford Companion to Aboriginal Art and Culture, Kleinart and Neal, Published by Oxford University Press, Melbourne, 2000. page 577, has to say. 'Dreaming can refer to three different, though closely related aspects of Aboriginal culture. The best known usage is linked to the idea of the 'Dreaming' synonymous with the '(Dreamtime)', which usually refers to an archaic, but eternal, time of ancestral creation closely connected to this is the idea of 'Dreamings' which is used when referring to particular ancestral stories, totems, and or physical manifestations of these. Finally 'dreaming' retains its usual English meanings with reference to nocturnal visions. The development of 'Dreams' and 'Deamings' as English gloss for Aboriginal and non Aboriginal communities.
Strethlow's translation for 'Alcherings" (Dreaming) is ('Out of all eternity,' from all eternity' and ever from the beginings')
