On a visit to the NGA in Canberra, the piece that was outstanding was the compilation of 60 canvases that made up David Hockney's Grand Canyon. In photograph, it doesn't look very impressive but in real life its size, scale and colour creates a sensurround experience. And it is very similar to the landscapes at Uluru and King's Canyon. The trees may be different but the rock formation is similar. The colours are just as astoundingly vivid.
