At first glance, street artist Julian Beever's sidewalk creations look like unfinished chalk drawings of oddly morphed animals or landscapes. But if you happen upon the one perfect angle, the image magically snaps into shape, showing you a giant charging snail or an aerial view of Times Square. Image courtesy Julian Beever
French street art duo TSF Crew create logic-defying works of art in the run-down areas of industrial France. Combining the cheeky thrills of a well-executed optical illusion with tst makes the perfect combination. Image courtesy of TSF Crew.

When it comes to admiring 3D street art, it's often a matter of perspective -- look at a street artist's design from one angle and it appears flat and distorted, but from another the illustration comes alive.
The process is called anamorphosis, and requires the viewer to stand at a certain vantage point in order to view the three-dimensional image. The optical illusions have been popping up around the world from London and Spain to New York and Denver.
While some street works of art are more advanced than others, one thing stays the same -- the perception of depth in a (technically) two-dimensional illustration.
