April 27, 2016April 29, 2016 S***e Like You Mean It The finished product. Context. Oil and water tanks originally designed for the electrical substation, which became legal graffiti walls in the 1980s. View up one of the silos. A shame the stairs are no longer accessible! I love the way light and shadow dance across the rusted surface as the sun moves overhead. Site: Casula Powerhouse Art Centre. Spraypaint on wall. My words find no home in your mind.
