Anamorphic images or text

Messages, images that can only be seen from the correct viewpoint, in this case not just a distorted texture on a single plane, but spread across polanes at differing depths and heights. See Gazerbeams message in The Incredibles, and the image of King Kong in Kong: Skull Island. Basically a tool that you can place a text/image shapre over from an inside the map view, and it will map the textures correctly to everything that it covers.
