Devices and methods for displaying images. The device for displaying at least one desired image comprises a set of at least two patterned templates, at least one of which templates being at least partially pervious to vision, the templates being movable independently of each other into predetermined positions and/or orientation(s) with respect to each other in superposed relationship so that the combined patterns form the desired image(s), wherein the pattern on at least one template is wholly unrelated to any desired image(s) and wherein the pattern(s) on the other templates represents the desired image(s) in an incomplete and unrecognisable form. The or each pattern comprises a plurality of spaced pattern element, the desired image(s) being formed by the juxtaposition and/or the superposition of the pattern elements as the templates are superposed. |
