Abstract:
1. A method of displaying images in either intelligible or encoded fashion depending on the relative position of two patterns, said method comprising the steps of: (a) creating a first said pattern, by providing an image and its enantlomorph on opposite sides of an axis of bilateral symmetry and selectively removing different elements from the image and its enantiomorph without removing the same element from both the image and its enantiomorph; (b) creating a second said pattern, being an enantiomorph of the first said pattern; (c) arranging said patterns for rotation relative to each other about a common axis with both said patterns visible to a viewer, whereby an intelligible pattern having at least one axis of bilateral symmetry is formed by a combination of said patterns at at least one position of said first pattern relative to said second pattern, where said first and second patterns are created by electronic means and rotated relative to each other by said electronic means.
