Vače oči
 

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.

Interesantno :care:

Meni se priviđa kako roze malo nestaju, pa se onda opet pojavljuju :D
Kul! :)

roze ti nestaju kad gleadš samo + a čim makneš malo pogled ima roza kuglice...a one su cijelo vrijeme tamo :D

meni isto djeluje blago zelenkasto,ali nista roze ne nestaju

jer se nemoš usredotočiti na + :D

kul :), roze nestanu skroz, a pogledam sa strane zeleni krug

Yap ako gledam normalno u rosa vidim rosa.. ako se fokusiram na plusic op postade zelena .... I bas je guba kako rosa kuglice nestaju i ponovo ... nestaju:lol2::D:D

Da ove optičke varke znaju bit fakat fora... :)
