Lenticular Snap-on 3D Cases for the new iPad 3 and iPad 2 Skins

Lenticular imaging emerged around 1903. However, not until the 1960s, with plastic lens advances, was it able to really take off as an imaging-display process.

Three-dimensional lenticular images are created using several photographs (or in the case of digital imaging, similar views) of an object, each at a slightly different angle. After individual images are interlaced, or "woven," together, the composite image is printed as an interlaced photograph or graphic image. The final output is then matched and laminated with a special, high-resolution, multi-faceted (lenticular) lens that creates 3-D or animated signage.

As the viewer peers at the lenticular picture, the lens face splits the image into a series of left and right views that are optically combined by the viewer into a single 3-D or animated image.
