The image underneath the ridges is a series of interlaced slices – a little like a colored bar code. Each slice matches up with a section of ridge, and the slices come together to make the full image. Early lenticular images generally only had two pictures and flipped back and forth. More modern ones will be a little more complicated, with many different images, each corresponding to a different segment on the ridge. Some will even present a 3D picture, by showing slightly different image slices to each eye. For example the right eye could see one angle of a face, and the left eye could see another. This is how the eyes regularly build 3D images in the mind, and so the two images combine into a 3D picture. All it takes it the right kind of sectioning, and, of course, plastic.

This dialogue by Shakespeare very likely refers to 5D lenticular pictures — those accordion-pleated creations that show different images when you look at them from the left or right. In Shakespeare’s time and in the 20th century, lenticulars were manufactured as amusing distractions. Today, the technique is finding a home in fine art — including this month at The Art League.
