Abstract: A lenticular lens case for a tablet computer, including first and second base plates that open to enable insertion of a tablet computer, and that close to firmly lock the tablet computer into place, first and second end caps connected to the first and second base plates, including tracks for sliding a frame inwards and outwards, and a lens frame for holding a lenticular lens, including extruding pins that slide along the tracks, such that when the pins reach the end of the tracks, the lens frame can be flipped approximately 180° over the base plates so as to tightly overlay a screen of the tablet computer, when the tablet computer is firmly locked in the base plates.
