Amazing illusion

[Nick.]

No really, it's programmed to change direction, watch closely.

No it isn't! Don't you understand? I can make it change if I look at it a certain way. I move my eyes the direction I want to see it and it changes. It's an animated GIF and would take too long too load if it automatically switches at random times, because of all the frames. It doesn't change. I can look at her and control my mind so it looks like she is only spinning half way round then back again. It's not a physic image.

It's quite relaxing just making it change.

Am I the only one who can't make it go the other way?

[Stephen!]

Jesus. It gives me motion sickness.

[Srieny]

It doesn't switch, I got my mate to look at it at the same time as me, it switched at different times for us both.

A psychology lecturer at my univerisity is using this in an experiment on visual perception and Dyslexia, its quite a strange illusion, but relies on the same principle as the Necker Cube.

keep at it, you need the shadow to make it change too. I look at the revolving motion of the foot in the shadow, normally makes i change for me.

I can only seeing it go clockwise and even when stirring and trying to picture it going anti clockwise i can't :eusa_wall

[LoveToStack]

I found it extremely difficult to picture it going the other way because when it goes one way it is profoundly clear that it is only going that way. I just look at the revolving motion of the foot and eventually it changes.

I sat there for ages, staring at the screen and I didn't quite see any change...
