Roxy Paine is concerned with beauty and the appreciation of beauty, in things which are often not necessarily considered beautiful. The principles underlying and guiding his work are expressed through the use of robotics, computers, and inorganic materials simulating and masquerading as nature.
Weed Choked Garden (2005), for example, uses stainless steel, thermoset plastic, and more to immortalize both natural process and neglect, as 13 species of weeds take over an untended vegetable garden in 88 sq ft of meticulously created chaos.
