Magic Eye Posters

There's a shark in this image, if you look carefully.

My high school english teacher would always show us these "Magic Eye" posters when we'd draw comparisons in class about an alternate dimension/universe/perspective. He said that if we relax our eyes and focus on the center of the image the true picture comes out beyond what we initially find.

These posters are "stereograms" that are "two dimensional pictures that can create three-dimensional images depending on how you look at them." I thought it might be interesting to share these with our current discussions of perspective and illusions.
