Andy Goldsworthy's hardcover books, Stone, Wood, Hand to Earth, Time etc are so enduringly beautiful. I wager, given a bit of time, you will never look at fallen leaves, or a cluster of stones the same. If you are not familiar with this Scottish artist, check out his doc, Rivers and Tides. If you aren't blown away by his creations, you will be impressed by the conditions he works in. My particular favorite is his timed piece, ice scupture at tide out. It's like a mini-art's thriller, as he fumbles with freezing hands against the incoming tide.
