来自摄影师Martin Hill 和艺术家Philippa Jones 共同完成的一组自然的艺术，一组来源于自然的人为的的“圆圈”。
In 1992 I became so concerned about products causing environmental damage because of their unsustainable design that I turned my focus to understanding and communicating about solutions to these design issues.
By creating and publishing environmental art my message of sustainability by design now reaches millions of people each year.
