Reuben's marvellous animals are the ultimate in upcycling - has corrugated iron roofing ever looked better? They have captivated many an overseas visitor, and can now be found in gardens all around the world. All the animals are individually cut from old recycled copper hot water cylinders or  corrugated iron, then assembled by hand. Once outside the animals age beautifully and require no maintenance at all apart from the occasional pat.  Of course.
