Far down in the wondrous county of Cornwall in the area known as Penwith is a play area with a difference. With the help of environmental artist, Melinda Hubbard and team, an area of boring space is being transformed into a natural play area. Even George Clinton, designer of the Brighton Earthship I mentioned some time ago has designed a high eco cave made from tyres based on his building at Brighton. There is a rain water harvesting tank which has water pumped into a bog garden through a granite tower by the action of the see saw.
