Uji mata

Assalamualaikum  wbt.  Takmau  cakap  banyak  jom  sesama  uji  mata.

It’s a simple one. 
How many pencils are there? 
There are clearly seven… what, wait! 
Six? No.. So how many?..
Look at
the bottom of pencils

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.

Stare at the moon long enough, 
and the stars should begin to fade away. 
How many can you get to disappear?

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.

Look at the red dot 
for a while and 
gray stripes will disappear

Although you don’t believe it, 
these lines are straight and parallel

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)

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.

Hover you mouse cursor 
over the picture. 
Does it move?

Are the walls of this house 
facing outward, or inward?

Which of these two dots is in the true center of the circle?
