1. An automated luminaire generating a modulated light beam along a light beam axis comprising: a Fresnel lens with a planar rear surface a stipple plate with a planar front surface and a stippled rear surface mounted adjacent to the Fresnel lens so that the planar surface of the Fresnel lens is adjacent to the planar surface of the stippled plate; the stipple plate is articulated to be selectively removed from the light beam and inserted in the light beam adjacent to the Fresnel lens; the stipple lens is partitioned into a plurality of separate sections and the stipple lens partitions articulations incorporate a pivot about which the partitions are rotated from out of the light beam to a position in the light beam immediately adjacent to the Fresnel lens.
