Two Faces or One?

Two Faces or One?
Our visual system constantly imposes three-dimensional characteristics onto two-dimensional images. While our interpretations of these images are usually correct
in ambiguous situations with more than one possible image our brain may not see all of the possibilities. In such situations
there are many factors simultaneously influencing our vision. Below are a few pictures that will help demonstrate this point.
