Olafur Eliasson (Icelandic: Ólafur Elíasson; born 1967) is a Danish-Icelandic artist known for sculptures and large-scale installation art employing elemental materials such as light, water, and air temperature to enhance the viewer’s experience. In 1995 he established Studio Olafur Eliasson in Berlin, a laboratory for spatial research. Olafur represented Denmark at the 50th Venice Biennale in 2003 and later that year installed The Weather Project in the Turbine Hall of Tate Modern, London.
