Here are a few illusions to stimulate your mind.
How many horses in this picture? (Should find Seven.)
Look at the middle column.
Where does it end?
Do you see four people?
Believe it or not, these guys are all the same height.
A face? ... Or, the word 'liar' ?
Do you see the word "LIFT"?
Or, a bunch of black splotches?
Focus on the dot in the center of the circle,
and move your head backwards & forwards.
The secret is to tilt your head to the left until you see the reflection
join the rock formation. You will see a woman and a child.
