Mind f**k thread

see now she wont go clockwise

and there are several copies open in different tabs

[Angstrom]

still clockwise.

I thought you guys were all taking the piss about the direction changing but my girlfriend came in and did the whole "wow it just changed direction, and again, wow! " thing.

I give up. She can stay clockwise, it's been an hour

I quote from the above site:

The spinning girl is a form of the more general spinning silhouette illusion. The image is not objectively “spinning” in one direction or the other. It is a two-dimensional image that is simply shifting back and forth. But our brains did not evolve to interpret two-dimensional representations of the world but the actual three-dimensional world. So our visual processing assumes we are looking at a 3-D image and is uses clues to interpret it as such. Or, without adequate clues it may just arbitrarily decide a best fit - spinning clockwise or counterclockwise. And once this fit is chosen, the illusion is complete - we see a 3-D spinning image.


By looking around the image, focusing on the shadow or some other part, you may force your visual system to reconstruct the image and it may choose the opposite direction, and suddenly the image will spin in the opposite direction.

This news article, like many others, ignores the true source of this optical illusion and instead claims it is a quick test to see if you use more of your right brain or left brain. This is utter nonsense, but the “right-brain/left brain” thing is in the public consciousness and won’t be going away anytime soon. Sure, we have two hemispheres that operate fine independently and have different abilities, but they are massively interconnected and work together as a seamless whole (providing you have never had surgery to cut your corpus callosum).


NICE ILLUSION THOUGH

holy shit!

both squares are 787878!!!

the really weird thing is I saved it to my PC then opened it in it's own tab in firefox and a tiny thumbnail of the gif is pictured spinning on the tab and it is spinning the same direction

that's slightly disappointing

I thought I had a new way of gauging whether I'm being too left brain! lol

[jb61264]

if you blink your eyes really quick, producing a "strobe" effect...you'll notice that she starts to touch herself

[xrayfish]

when i look at it early in the morning when i start work she is usually going clockwise, then when i wake up she starts going the other way.

Ive got it - look at the foot that sticks out. Say to yourself 'left foot left foot' and it rotates anticlockwise.

Say 'right foot right foot' and it goes clockwise.

Hours of fun for boys and girls

[Hedroom]

Yeah, with practise you can get her to change whenever you want.

[Hedroom]

In fact... maybe you can get her to DO whatever you want

[djgroovy]

95% of the time clockwise, 5% anti-clockwise.
And i thought i was too left-brained sometimes! Whoohoo, when i'm feeling uncreative from now on, i'm looking at her!

I'm a dominately clockwise brained monkey. got her to spin the other way by blocking out all but her knees and expanded from there. freaky stuff.

[djgroovy]

As for the squares, the illusion comes from the fact that all the squares around B are darker, and all the squares around A are lighter, which fools the eye.

[sporkles]

Hey - this is ace. I hope more stuff like this turns up in this thread. It's pretty
easy to change the direction on the animation. Focus on the reflection
underneath the figure, and think "(anti-)clockwise", i.e. the opposite of what
you're seeing by default. When you've convinced your mind that you're seeing
the opposite, move your eyes upward, and you've changed the direction.

[sporkles]

Not nearly as cool, but still... And I believe we have CW on this board too
