Animal Shadows Optical Illusion

Jeff Bilinovac sent me this funny looking photo of an animal kingdom. If you look carefully, you’ll be able to recognize bunch of animal shadows. What is even more interesting, is the fact that the author had to be very creative to think of this, and manage to integrate all the shapes, for them to fit perfectly. If I’m correct, this effect was first discovered by M. C. Escher. Check his awesome drawings in the appropriate category, or simply check “Best of Escher” article.
