George, great article you've posted here! All this nature inspired design makes me thing of the work of Andrew Goldsworthy - Scottish artist Andy Goldsworthy uses a seemingly infinite array of purely natural materials, from snow and ice to leaves, stone, and twigs in the creation of his one-of-a-kind sculptures. Unlike such artists as Christo and Michael Hiezer, whose works leave definite marks on the landscape, Goldsworthy's approach is to interrupt, shape, or in some other way temporarily alter or work with nature to produce his fragile, mutable pieces. What I wouldn't give for one of his stone cairns in my yard! I was inspired by his work after viewing a DVD from netfix, so I've checked out his photography books, too. I found his play on nature's patterns to be inspirational in my home garden design as well within my home. Think of all the current rave of natural stone used in today's counter-tops - people love having their own piece of nature in their kitchens/baths.
