Hill of Poisonous Trees (three men) (2008) exemplifies the artist’s signature photo-weaving technique, in which he collects diverse found photographs—portraits of anonymous people, stills from blockbuster films, or journalistic images—cuts them into strips, and weaves them into new composition. The title of the series is translated from the Khmer phrase Tuol Sleng , which literally means a poisonous hill or a place on a mound to keep those who bear or supply guilt, and the photographs came from the Tuol Sleng Genocide Museum in Cambodia, a former prison where at least 200,000 Cambodians were executed during the reign of the Khmer Rouge between 1975 and 1979. In this particular image, three men stand against the backdrop of what looks like a prison interior.
