 This piece demonstrates characteristics of environmental art through Koh’s use of recycled materials and the ways in which she turns used and discarded items into a working piece of art.In a similar artwork called "Lumber" (1991-1994, dispersed 2002), Koh makes use of flexible pieces of recuperated lumber glazed with oil and marine varnish to be installed alongside select architecture.Various projects by Koh are also collaborative or rely on the active participation of its audiences.
