A preferred embodiment comprises a dynamic display based on a program image element which will only generate a preprogrammed image. As an example, the image element may comprise electrically-driven MEMS mirrors. This example may be embedded in an ID card. At the time of issue of the ID card, pixels in the mirror array will be permanently programmed as either ‘alive’ or ‘dead’ in a pattern matching the photo of the person in question. When stimulated, only ‘alive’ pixels will actuate, creating an image for comparison to the adjacent printed photo. Due to its dynamic behavior, delicate mechanical structures, and single-time hard-wiring, duplication of, or tampering with, this secondary dynamic image will be nearly impossible. The ID car is but one exemplary application and other embodiments, applications, and methods are described in the specification and claims.
