chalk art and the brain

Fun.  For more by this artist, Julian Beever, see here.   Which of the different ways a Beever drawing looks when seen from different perspectives is the "real" one?  Along similar lines, which of the sounds different people (or animals) hear a tree make does it make if there isn't anyone around to hear it?
