Optical Delusion - Can You See The Black Dots?

A neat visual trick. Try this.

I can see the 12 black dots in the second image.
The first image has no black dots...

 

You can see them all @ once? I only see one @ a time!

If you follow the twitter feed another is -
find the intersection -

 

There is no intersection.

 

DavidGP would say you have good eyes my friend.

 

I'll confess...
I checked the first image with a colour picker.
Depending on where I focus, I can clearly see 4 dots at a time in the second image.
With the third image, you start at the top block and complete the circle. Do the same with the rest of the circles, starting at the top.

 

My eyes hurt now... I also did not see an intersection in post #3.

 

I had some san gria and thought that influenced the effect. It is hard on the eyes (and mind)!

 

Can you see these two blocks are the same colour?

 

maybe same color but more reflected light in the lower half

 

Put your finger over the line where the boxes meet.

 

The Black Dots pic, I can only focus on 4-6 at a time and they come and go. Kind of makes you dizzy.
The Where Do They Cross pic, they don't.
The Two Blocks Same Color, to me it is two shades of grey. Interesting we don't all see the same thing.

 

this is a massive site for these sorts of things, you could spend many hours looking through everything this guy has created.
