Head over to Paradis Express to see a wide range of stone spheres.
Delphine has posted a wide range of them, many sizes, though sadly uncredited as to maker or location. The spheres are perfect in themselves, anchoring the area around them through their mass. I get a really visceral sense of the space surrounding them. How do you perceive the spaces that surrounds them?
Would you place them differently? Would you put them in your garden?
