We describe a three-dimensional halo demonstration experiment. A volumetric arrangement of crystals is used to project a mosaic halo display upon illumination. The demonstration can be used to convey the collective scattering aspect of the natural halo mechanism and at the same time vividly portray the concept of orientation classes in the context of halo theory.
