Abstract
A security device includes an image projection system that includes an array of focusing elements (101) and an array of image icon elements (103) disposed relative to each other such that a synthetic image is projected by the image projection system. This synthetic image, along with at least one other image functions as a targeting image. As targeting images (310′, 310″), these images are spatially coordinated such that a reward image (350), which is otherwise at least partially hidden, becomes revealed upon the targeting images having a predetermined transformation. This targeting effect functions as a game that attracts the attention of an end-user of high-valued articles of manufacture to which the security device is attached. The security device allows a viewer to actively interact with the security device by trying to turn on the reward image.
