Abstract
There is provided a system and method for selective viewing of a hidden image within a displayed image. There is provided a method for providing a composite presentation, comprising displaying a plurality of elemental presentations including a first presentation and a second presentation to provide the composite presentation, wherein the displaying of the second presentation makes at least a first portion of the first presentation become unrecognizable to a human eye viewing the composite presentation without a use of a visual aid. This rendering of the first presentation as unrecognizable to the human eye may be accomplished through filtering techniques such as one or more of optical polarization, shuttering, depth of field alteration, light intensity alteration, light angle alteration, anaglyph filters, and other filtering techniques.
