Abstract
Latent effects projection systems that allow a latent effects projector to be used in connection with various materials, such as wall pieces, floor tiles, signage, hangings, and the like; use reflective polarizers having various looks and/or which allow for the development of different color palettes; which are relatively insensitive to heat; and/or use plural retarders to generate relatively more saturated colors and/or latent colors that are substantially repeatable.
