Andy Goldsworthy's Land Art In the land art movement, no name is bigger than Andy Goldsworthy. The British artist is recognized around the world for the ingenious sculptures and art installations that he creates using elements found in nature. Fallen leaves are among Goldsworthy's favorite tools, and he often uses the contrast between brightly colored leaves to create dramatic geometric shapes.
