Claim:
1. A display apparatus, comprising: a static content layer comprising a plurality of images; and a lens array overlying the content layer, wherein the lens array comprises a first set of lenses each with a first width and a second set of lenses each with a second width differing from the first width, wherein the lenses are elongated, cylindrical lenticules and the images are elongated, interlaced images, wherein the cylindrical lenticules of the first set of lenses each have a first radius defining the first width and the cylindrical lenticules of the second set of lenses each have a second radius, the first radius differing from the second radius to define the first and second widths of the first and second sets of lenses, wherein the content layer comprises a first portion with a first spatial frequency and a second portion with a second spatial frequency differing from the first spatial frequency, wherein the first spatial frequency is less than the second spatial frequency, and wherein the first set of lenses are aligned with the images in the first portion and the second set of lenses are aligned with the images of the second portion, whereby the first and second widths are defined based on spatial frequencies of the content layer.
