The Bactra Review   Andy Goldsworthy: A Collaboration with Nature
There is incidentally a psychological puzzle here. Anybody who sees a picture of one of Goldsworthy's works recognizes at once that it's not a natural arrangement. So far as I know, nobody has a clue about how we do this. I shall refrain, with some difficulty, from elaborating on the difficulty this poses to those of us who want to study self-organization in nature.
