An optical illusion device and method of production is described. The method comprises producing a digital sculpt. A rendered visual image and a thinned digital sculpt are then produced from the digital sculpt. Next a digital thickness shell is produced from the thinned digital sculpt. Finally, the rendered visual image is employed to impart a lithophane depth map onto the digital thickness shell. The overall result is an optical illusion device comprising a negative image forming surface with a registered lithophane image imparted on thereon. When the optical illusion device is viewed from various angles (and with a light source placed behind it), the negative image forming surface appears to the viewer as a positive or convex model with a photographic image applied to the profiled surface. The illusion created is of a panning, three-dimensional photographic image, complete with improved detail due to the presence of the lithophane depth map.

A system and process for injection molding polymer articles is described. The system and process are designed to reduce gate blush. In one embodiment, an injection molding device injects a molten polymer composition into a mold cavity adjacent to an interior curved surface on the mold. The flow of the polymer material is parallel to a line that is tangent to the curved surface.
