Anyone in the vicinity of Sydney over the next few months should visit the must-see exhibition of acclaimed artist Olafur Eliasson. Renown for his ability to emulate nature - from creating the sun inside London's Tate Modern (The Weather Project, 2003) to waterfalls under the Brooklyn Bridge (The New York City Waterfalls, 2008) and, perhaps most famously, making whole rivers run a deep green colour (Green River, 1998-2001). Breathtakingly diverse, magical and immersive, Eliasson makes artworks of the simplest elements of the world around us. The first survey show of his career is open in MCA Sydney until 11 April.
