Abstract: A security device includes an arrangement of image icon focusing elements, wherein each image icon focusing element of the arrangement of image icon focusing elements is associated with a focal path. The device further includes an image icon layer with one or more image icons associated with a first characteristic color and one or more image icons associated with a second characteristic color and one or more regions between the image icons comprising a volume of substantially colorless material. At a first viewing angle, a color is visible through each image icon focusing element, and the color visible through each image icon focusing element at the first viewing angle is based on one or more of the first characteristic color, the second characteristic color, or the substantially colorless material.

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.

Abstract: An optical device that produces flicker-like optical effects is provided. The optical device employs directionally cured image icons. Specifically, the optical device is made up of at least one arrangement of image icons formed from one or more cured pigmented materials, and at least one arrangement of optionally embedded focusing elements positioned to form one or more synthetic images of at least a portion of the arrangement(s) of image icons. Some or all of the pigmented material(s) is cured using collimated light directed through the focusing elements toward the arrangement(s) of image icons at one or more angles relative to a surface of the optical device to form directionally cured image icons. The synthetic image(s) of the directionally cured image icons is viewable at the cure angle(s) and therefore visually appears and disappears, or turns on and off, as the viewing angle of the device moves through the cure angle(s).
