Perspective is everything.

A friend sent me an email with some images of work produced by artist Julian Beever that dramatically demonstrates the importance of perspective.

This first image of pavement art is one viewed from the perspective intended by Beever.



This is the image from the "wrong" perspective.



As I understand it, this type of work represents an optical anamorphose, a specific case of anamorphic images which one site defines as "optical perspective toys."
