It could be a bunch of artfully placed sticks or a mosaic of different colored leaves, or even a careful arrangement of stones! British sculptor, Andy Goldsworthy is renowned in his field for his unusual outdoor art installations, which, believe it or not, are created solely with whatever he finds lying around outside! His art works may not last long enough to make it into a museum or gallery, but if you like them you can order the photo book from Amazon.
