It has long been observed that the human eye recoils from absolute flawlessness because it offers no point of connection. By contrast, we embrace imperfection and transience. We find beauty in things that are imperfect and decayed, in blemishes that only time can create.

Mark Hilltout was always drawn to the random, the discarded and the broken. Car dumps fascinated him. He was attracted to the broken edge not the perfectly straight line. He saw beauty where others saw ugliness. For 12 years he looked intently at something that most of us try to ignore. Corrugated iron. (The word comes from the Latin ‘Ruga’ meaning to wrinkle or crease). To the conventional eye, this is a poor man’s shelter to be used only in the absence of alternatives, a reminder of global inequality. Yet almost 2 centuries after its invention, it remains indispensable.
