1. A lens system for modifying the cross-sectional geometry of a projected light beam comprising:

  • a lenticular lens with lenticular elements having an angular orientation as viewed by the light beam;

    a rotatable mounting for the lenticular lens which positions the lens relative to the light beam so that only a portion of the lens will intercept the light beam and as the lens rotates different portions of the lens intercept the light beam wherein the angular orientation of the elements changes relative to the light beam can vary between zero and over 180 degrees; and

    a second moveable lenticular lens with lenticular elements wherein the second lens is moveable relative to the light beam such that the lens passes through different portions of the light beam.
