Streets give an illusion of permanence; their concrete slabs and rows of buildings fixed addresses with immutable histories. In fact, streets change names, open or close off, and disappear altogether. Sydney is unique in that it grows without plan or direction. There is a difficulty in reading old maps of Sydney, because it has gone through more changes than any other city in Australia. Names disappear when ideas transform.

A picture is worth a thousand words, says a proverb coined at the new dawn of advertising. But words are all I have to convey the images that I cannot see. And most people seem to think that someone who is blind has no interest in art.
