April is traditionally a month when we fool our family and friends. This year, try fooling yourself.

Optical illusions are illustrations or photographs that can trick your mind in many different ways. Sometimes you see things that aren't there, sometimes you see things that should -- but don't -- make sense.

Note: The Eye-Fool's visual tricks are often puzzles without solutions. If you're looking for answers to these bizarre images, don't bother. Instead, introduce a friend to the Eye-Fool's illusions. Chances are, they won't believe their eyes!
