Shilpa Gupta’s Speaking Wall uses bricks, headphones, a small screen and a sensor. The viewer moves along a line of bricks while a voice responds to their position. A wall normally tells the body where it cannot go. Here the boundary begins giving instructions. That reversal makes the work unsettling: something built to separate becomes strangely intimate because it knows exactly how close you are.
