This installation is a powerful reflection on the absurdity of political boundaries, in this case, the Green Line. The Green Line refers to the 1949 armistice lines established between Israel and its neighbors—Syria, Jordan, Lebanon, and Egypt—at the end of the 1948 Arab-Israeli War. Its name was derived from the green pencil used to draw the line on the map during the armistice talks. In June 2004, Francis Alÿs performed a walk in Jerusalem holding a leaking can of green paint, following a portion of the Green Line. Israelis and Palestinians were invited to react spontaneously to the action. Ilona Katzew, 2008
