In his corridor pieces, Nauman's sculpture assumes the dimensions of architecture. The spaces in these corridors are often claustrophobic yet they seem to extend infinitely, like a corridor seen in a dream. In this piece, the extension of space is achieved by the placement of a mirror set at an angle at the end of the corridor. Some of Nauman's corridors are areas in which he or the viewer performs by entering the space. This is impossible here; the width of the corridor has been narrowed to make entrance impossible, thereby heightening the sense of eerie isolation in the piece.
