my dad just showed me an e-mail he received from someone else, and i thought i'd pass it along:
If your eyes follow the movement of the rotating pink dot, you will only see one color, pink. However, 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, 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.
For me, the "rotating pink dot" was actually a circle of pink dots with one of
them disappearing at a time (clockwise), but the rest was as the e-mail
described. My mom tried it and said the pink dots never disappeared when she
looked at the "+". I'm curious if anyone would know why she's so special (in
this regard) or if others experience something different as well.

2005/11/18 14:19 DavidSame reaction as you, one green dot at a time goes round, BUT when I take off my glasses, that have antii=glare treatment from Walmart, there is a green blur slightly above and to the right of the pink dots, but I can never make them go away. Most strange
2005/11/29 13:12Hmm, Nancy, so you see a green blur rather than a dot? How big is the blur? Is it the same size as a pink dot?

Quite technical (full grasp requires studying at least other three articles in the same journal) but worthwhile
