Does your brain work?

If your eyes follow the movement of the rotating pink dot, you will only see one color, pink.
If you stare at the the black + in the center, the moving dot turns to green.

Now, concentrate on the black + in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a 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.

My brain works just fine thank you. Something odd I noticed, when I take my focus off the cross and move it just a little off the side of the cross, I see a ring of green dots against the grey background. That ring of green dots aren't there to begin with, it just happens to be there because of my vision (or maybe my eyes suck more than I think they do). This all has to do with how our eyes recieve light. Of course that's how we're able to see to begin with, but when thing's are flashing/moving/any other activity, then that might affect how we perceive colors.

As for the box thing, shadows are quite interesting. I don't know what to say about that.

To think I learned how our eyes work on a Food Network show. XP But then again, you probably want an opinion from someone who has 20-20 vision. Haha.
