Cornerstone Festival: The Art of Landscape Design

NPR has an audio story (with pictures) on the avant-garde Cornerstone Festival: The Art of Landscape Design.

This is a collection of gardening as art form, focusing on hardscape and artwork as oppossed to traditional plantings and plants. It sounds like an excellent place to get you thinking about both gardening and art and developing new ideas for your own garden. Much like high fashion, you may not want to duplicate these gardens, but you might find your own ideas within.
