A group for photos of environmental art, either created by yourself or others (e.g. Andy Goldsworthy, Richard Long).
The artworks I have in mind are those created from the environment, e.g. stones, sand, leaves, petals etc. etc. They are in harmony in nature, and tend to be transient, returning to the environment from which they were created (e.g. beach circles erased by the tide).
This is not a group for environmentalist photos. I am sure there are fine environmentalist groups out there on flickr; this isn't one of them.
