Recently I went to the Guggenheim in New York to see the Christopher Wool exhibit which I enjoyed but was completely taken by a side gallerly curated by Lauren Hinkson named "Lasting Images". The piece that drew me in by Mona Hatoum was vertical wires suspended in a cube which shifted and changed as you walked along side it. On closer inspection you saw the the wire were actually barbed wire.... "it's ethereal form belies a forboding presence."
