Anaglyphs are strange pictures in which both images are sort of laid on top of each other. Anaglyphs can be very confusing and may look like a blurry picture.
However, if you put on special glasses that filter out the right eye image in the left lens and filters out the left eye image in the right lens then your eyes will see two slightly different pictures in each eye, thus producing a perception of depth.
In these pages, we use different colour biases (you could also polarize the images in orthogonal orientation) for each image. You will simply need some red-green glasses that were once popular for comics and movies back in the fifties. Or, you can get some red and some bluish/green acetate and fix them over your reading glasses.
The Red lens should be over your left eye.
Because the colours are distorted, this is my least like method although some pictures work very well using this method.
DON'T FORGET TO TAKE THESE OFF WHEN YOU LEAVE YOUR COMPUTER!!!!! Otherwise people may look farther away than usual (only because they are keeping their distance from a crazy person).
