Christo and Jeanne-Claude's works are entire environments, whether they are urban or rural. The artists temporarily use one part of the environment. In doing so, we see and perceive the whole environment with new eyes and a new consciousness. The effect lasts longer than the actual work of art. Years after every physical trace has been removed and the materials recycled, original visitors can still see and feel them in their minds when they return to the sites of the artworks.
