So, where is the frog?
Camouflage creates its own kind of illusion. Nature thrives on it, and optical illusions often befuddle humans.
S. Tolansky, a former Professor of Physics at the University of London, wrote a small treatise dealing with visual illusions. And he argues that camouflage is a practical use of optical illusions. Camouflage is used by animals and plants primarily as a means of protection from predators and by humans for warfare. But all illusions are dependent on the health of the eye; severe astigmatism can destroy the illusion featured below. Yet, it is well to remember that things are not always what they seem!:
