'ZOBOP' is Lambie's signature work. It is different every time it is installed, as it varies according to the shape of the room. Strips of coloured vinyl tape are stuck down on the floor, beginning at the perimeter of the room and continued until the tape reaches the centre. Thinking about the kind of art which was being made in the late 1990s, Lambie realised that colour seemed to be either over-controlled, or drained away. He therefore decided to make something super-coloured, psychedelic even, but which still retained a strong conceptual base. The work is based on the concept of trying to fill a space while still leaving it empty.
