      We report the implementation of a system for displaying
      three-dimensional animations based on holoprojection.  It is
      based in the holoprojection of two-dimensional slices (produced
      by a modified ray tracing program) of three-dimensional
      scenes. The final display is a truly spatial three-dimensional
      image with continuos horizontal parallax. It makes use of the
      holographic screen, a special diffractive lens, freeing the
      viewer from visual accessories.
