If your eyes follow the movement of the rotating pink dot, you will only see one color, pink.
If you stare at 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 if you're lucky!

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.

That's a trip! Thanks for sharing!

If you stare at the picture for awhile you are supposed to be able to see a waterfall appear...
...I still haven't seen it!

I guess some people see a boat somewhere in the foto...but it doesn't seem to work for me.
