Amazing test

【呢個係幻覺測試】

(1)  如果你嘅眼睛係跟住粉紅點移動嘅，嗰ｄ點會保持住粉
    紅色嘅狀態

(2)  但當你凝視中央嘅黑色十字符號，移動緊嘅粉紅點，就
    會變成綠色

(3)  而家你集中注意力望實圖中黑色十字符號，一段短時間
    後，所有嘅粉紅點會慢慢消失，你只會見到一個綠點喺
    度轉動．

我哋嘅腦袋運作係咪好神奇呢~ 其實係冇綠點，仲有就係

粉紅點從來冇消失過，咁就足以證實，We don't always

see what we think we see~

"Amazing TEST~"

If your brain works normally this is neat.
This is another example of an amazing illusion!!! The last sentence is so true.

If your eyes follow the movement of the rotating pink dot, the dots will remain only one color, pink.


However if you stare at the black '+'  in the centre, the moving dot turns to green.
Now, concentrate on the black ' + ' in the centre of the picture. After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.

It's amazing how our brain works. There really is no green dot, and the pink ones really don't disappear. This should be proof enough, we don't always see what we think we see .
