A very interesting collection of optical illusions.
1. It’s a simple one. How many pencils are there? There are clearly seven… what, wait! Six? No.. So how many?
2. Close your left eye and stare at the cross. As the circle moves left and right, it should pass through your blind spot and disappear completely! You may need to lean in closer to get this to work.
3. Stare at the moon long enough, and the stars should begin to fade away. How many can you get to disappear?
4. Can you tell which of these lines is longer? Test them with a ruler or a piece of paper -- you may be surprised.
5. How many colors do you see? Most people see four colors: green, blue and 2 shades of pink.

6. As the small circles intersect with the large ones, we seem to see the outlines of a growing and shrinking square. But there is no "square" -- your brain is trying to visualize in terms of solid shapes, and fills in the blanks.
7. We already had an entire post with such pictures that seem to be in motion, but nope, the aren’t moving.
8. Look at the red dot for a while and gray stripes will disappear
9. Although you don’t believe it, these lines are straight and parallel
10. These two birds are identical, not only in size but in color too.

11. These "fish" may appear to be wiggling, but the only thing changing in this animation is the color.
12. What do you see here at first glance? The yellow arrows pointing to the left or green arrows pointing to the right? There is no correct answer. Different people see different arrows at first (I saw the yellow ones)
13. Another "false spiral" -- actually a series of concentric circles, hard as it may be to believe. To prove that there's no spiral, try tracing your finger around one of the circles. You'll see that it never moves inward or outward.
14. Do you see the rose spots? Well, if you look at the cross, soon enough there’ll only be one green spot running around, other spots will disappear.
15. First, look at the image at a close distance, then look at it from 1 meter distance
