Interessante Skulpturen schafft Robert Cannon, der seine Kunst folgendermaßen beschreibt:
Terraforming is a concept devised by the aerospace industry to describe the process of creating a habitable environments in uninhabitable places, like Mars or the Moon. I pirated the term to bring it to bear, through the works, on modernity, capitalism, indeed the whole Civilization Project which seems to me uninhabitable in certain ways. The Green movement seems too often left up to the engineers and activists, who bring science and passion, but the movement also needs vision, experiments in real Green Art, in Green Dreams, and Green Meaning and I see the Terraforms as one of these experiments.
The Terraforms are constructed of hollow shells of ferro-cement or metal with earth sculpted up through the voids and planted in the exposed areas. Terraforms do grow and change with the seasons. Like the proverbial canary in a coal mine, they are very reflective of the qualities of their environments, natural and social. They would over-grow themselves if left to return to nature, or whither and die if locked away in some storage room, or remain balanced if cared for in a healthy environment.
