Outstanding. I read John Berger (as everyone did) at art school, and am always fascinated by this stuff. What is the psycho-perceptual reason for the movement? Any ideas?

If someone had shown me that back in 1967 I might never have recovered!

If you turn the screen on edge it almost stops. If you stay focused on one small area it stops completely.

I showed it to my wife. No movement at all. Weird. It made me feel almost seasick. I can stop it if I stare really hard at it.

I perceive slight movement in the image as i shift my point of focus across the image but cannot perceive any movement when my eyes are still. Is that what other people see or so you see constant movement?

My perception is a bit off when it comes to these things. For example, no matter how much I try, I can never see any of those Magic Eye things.

Definitely more movement as my eyes wander about the image for me.

dont see anything at all except the image... then i read about movement, and sort of , a bit , maybe, or not, but nothing earth shaking...am I missing something?
have a couple of beers and stare at the wallpaper, and stuff moves around.....

For me there is an hour glass shaped central pillar, constantly rolling clockwise against the ball
