DavidMcC wrote:Well, the one featured in Macdoc's post #11 is a static one, and would work, as you say, without a TV screen, however, others would not (eg the one in post #12).

The one in 12 is literally a moving image (.gif). Not one -

I think there would be more justification in me saying that to you, Scott.
EDIT: Like TE on another thread, you are totally ignoring the OP topic, in order to throw insults around like confetti. Sad, really.

... I hope you realise the damage you are doing to the credibility of this site in the eyes of surfers, especially as the mods allow it to happen.

Your eyes are ok. It's your brain that's the problem.

Have you bothered to test your bullshit before posting it?

I printed the illustration shown in post #11 as a few others out on paper a few years ago. Same effect. My cat detects the illusory movements on the printed paper too. When I leave them on the floor she tries to trap the moving bits under her paws. She Ignores printed sheets without apparent movement or just sits on them.

She never flips for me. She's always anti-clockwise. I can't even see how she could be the other way. I suspect it's because my imagination loads her with too many assumptions in my 3-D visualisation of her, that's to say I see her as a solid not as the flat that she is.

Always clockwise for me. Like you, I just can't get the opposite direction to work, no matter how many times I focus elsewhere, or go away and come back.

I do it by focusing squarely on the pony tail first; then you can see the artifice in the animated gif. Changing the focal length by a few centimeters helps, when I get stuck on one orientation. When you feel you have some control over the orientation, you might no longer think of it as an optical illusion. Maybe this is a 'persistence of vision' thing more than a cognitive illusion, after you master the control.

Weird, isn't it? I just gaze at the ballerina. Every ten or so seconds she reverses direction spontaneously and without any transition.

I find that it’s easier to flip the rotation of the ballerina if I move the image to my peripheral vision. That is: shift image to peripheral vision, do the flip (visually alter... with your mind the direction you want), and then move the image back from peripheral vision. Et voilà.

ETA

I mean, flip at will, of course.

O_O Oh my. I assumed these optical illusions would only work for humans. Need to go find a cat or doggie and do some science with them now.. :mrgreen:
Well that was awkward.

Don't bother. It's been done for you.
