Try This!
Well, I was kind of bored at home, so I did a search for lame stuff online, and found this optical illusion rather interesting. See if you can get it!
1. Stare at the black crosshair in the center. Do you see the moving dot turn green?
2. Now, concentrate on the black crosshair in the center of the picture. After a short period of time, do you see all the pink dots disappear and only a green dot rotating? (It took me quite a while to get this.)
It’s amazing how our brain works. This optical illusion itself should be proof enough, that we don’t always see what we think we see! 
yes, i can see… it’s fun, hehe.

QQ: I think it’s still considered as optical illusion.. cos somehow ur brain and ur eyes cause confusion and it makes you see green when there wasn’t actually any green dots.
