I can't remember her name, Lottie something or other, but a German artist up in Durness (top bit of Scotland just before you fall in the water!) makes these lovely ceramics, takes them out into the wilds, photographs them in situ - then walks away and just leaves them there for others to find. Part of the 'art is ephemeral' sort of idea, she never knows what happens to them! I like that concept, no bullshit at all.
