Changing by alteration in view-point of observer. - In order to give changing colour effects as the observer moves, slats 4 of coloured glass are interposed between a stencil 1 and diffusing glasses 2 lighted by lamps 3. In daylight signs of the forward stencil type the slats 4 are arranged as shown. They may either be inclined or at right angles to the stencil. Slats may also be superposed on the stencils of davlight signs of the overhead type. In some cases they may be opaque.
