Mona Hatoum, Corps Étranger (1994) Produced with the assistance of a surgeon. The video maps an internal and external self-portrait of the artist through such complex medical procedures as endoscopy, colonoscopy, and echography. The video is projected on the floor within a circular booth and is accompanied by a soundtrack recorded from the artist's internal organs. The equally dramatic installation Light Sentence (1992) is a dark, cell-like room enclosed on three sides with wire mesh. Hanging from the ceiling is a single light bulb, which is continually lowered and raised, creating disorienting shadows on the wall. The effect of the piece is alternately vertiginous, frightening, and eerily beautiful.
