Thats interesting, even though they show you that it slants down, it looks like there is a magnet in the middle that is attracting the balls.

Looks to me like the spinning girl actually does change direction although I don't know how much or what parts of the actual animation file change. I don't see how the apparent lead with the left (and then the right) arm could be illusory.

Hints?

That would be cool.

and its use as a study of schizophrenia.
there is also a cool study of the brain that showed that schizo is actually just the fact that some folks brains don't have the half second delay that everyone else has.
was written up along with the study of the fake hand being touched.

there is also a japanese researcher that claims that ALL the opticlal illusions are the brain trying to locate the parallax of the "end" of the illusion to judge distance.
some cool studies on computer screen opticals that show directional changes from font sizes stacked in interesting ways.

Something odd about this one...
My mom has the beginnings of Macular Degeneration, we watch her eyes closely. She doesn't see the illusion in this at all. Looks like a perfectly fine picture to her. Maybe it's a new eye test to use. We have a few that are used to track the damage.

Where do they cross?

Bright sparks remind others that they too can dance
What I am looking for is looking for me too!

Yes, something odd...  like there are four circles that do not cross?

Well, I meant it's odd that she sees absolutely no illusion.
All she sees is four circles just sitting there. They don't look like spirals or wiggly or anything.
Macular Degeneration is all we can think of.

I can see both.     When I concentrate on what I am looking at, I see 4 circles.
When I just look at it, my mind badly wants it to be a spiral!  Even as I tell myself it is not!

There is an old saying
What are you looking for?  And what are you looking at?

On that image, Where do they cross? I don't see four circles.  I am not sure where they intersect.

Find the black dot ... it is in the white dots when it flashes.
