Space 14 2013: Illusions

Can you count the black dots?

The Sort Of Optical Illusion That Grows On You

Stare at the black center. Do you see it getting bigger? Guess what. It’s not changing. Really it’s not. It’s the same size. But our mind thinks it is.

Pink Dots

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 center, the moving dots turns to green. Now, concentrate on the black ” + ” in the center 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.
