A steel folding screen with the text of a poem by Charles Baudelaire.  The poem, "Correspondances", is from the collection "Fluer du Mal".  There are four hinged panels, each of which is six feet tall by eight and a half feet wide and one inch deep.  There are various configurations these panels can be arrange in.  My current favorite arrangement is as a pentagon, approximately fifteen feet across, with one side open and the text readable from the inside.
