An apparatus forming a border for an image comprises a first pattern (3) and a further pattern (4) superimposed on but spaced from the first pattern, the patterns comprising visually contrasting areas, overlying portions of the first pattern and the further pattern being such as to form a resultant pattern (5) appearing to lie in front of and/or behind the plane of the border. The first pattern and/or further pattern changes with time and comprises a liquid crystal panel comprising an array of addressable picture elements.
