 Yes. Does that mean I´m drunk?

 No, it means you are shallow.

Or we are both drunk!

 Which one last the longest? Being drunk with you or being shallow?

 Being shallow can go on and on.....being drunk takes too much maintenance.

 They are not,but if you looked at them as a whole you would think they are .

 Neat! Reminds me of my Art Class days...we studied these sort of things, learned to find them in old Masters works.

Hmmm....can´t get rid of that extra box there. Are you an art student? We studied this. These devices are used by all artists, but most of the time in a very subtle manner. 

If you carefully study this painting, you can see some devices that cause subtle illusion of movement.

It depends on the elephant´s gender

Just look at on the " + "  for a few sec, and you will see the all of pink points will be disappear interesting ...

Can you see the dolphins ?

 dolphins ...no naughy lady yes ha ha....(sapik rules ok!!)

Even more interesting!!  For me the pink dots DON´T disappear but after a few seconds I also see revolving GREEN dots!!  What does this mean??  - any ophthalmologists out there??

 lay off the booze for 24 hours.....

 hmmm , its interesting , just try again to look straight only on the " + " , you will see the pink dots will disapear.. and dont worry about Green dots, its very normal

 I looked straignt at the + for quite a few seconds and still did not see the pink dots go away. A green dot appeared that went around in a clockwise direction around circle.

 You are a bit slow

That part happens as soon as you look at it - then the pink dots all gradually disappear!

 Just could be my eyes are not the same as yours. I have amblyopia and am functionaly blind in one eye...............so we don´t see eye to eye.

This is really Unbelievable  !! Just check this test...

Here

 Grrrrrr it is so annoying, the website is blocked from my work pc!

 i agree with you ... But you can check this later   ( you will not believe your eyes )

OH MY GOD!!!!! Allah Allah !!! I can´t believe this!!!! it is  100 % right !!! but but how can it be possible?

 i did try many times , yes you are right its %100 right , i realy dont know how its possible    weird

i just figured it out shall i tell you ?

 evet

The thing is.... no matter what number you think of, when you subtract total of digits from original number, the answer is always multiples of 9... like 9, 18,27,36.... and if you look at the table attentively you will see the symbols beside multiples of 9 is always the same

 I have sort of half figured it out!!  - oh I was on the right lines anyway!

 yessss i figured out now. very clever..
