Rotating snakes: Miscellaneous

I produced several variants of "Rotating snakes" because this work seems to be preferred by many people.

since Fubruary 27, 2006


"Two snakes"

The outermost snake appears to rotate counterclockwise or to be stationary while the rest appear to rotate clockwise.

"Rotating snakes: gradation version"

Each ring appears to rotate slowly without effort. In this case, the direction of rotation is constant. When observers keep blinking, each ring appears to rotate quickly. In this case, the direction of rotation is not constant. Attention can change the direction.

Warning: Do not keep blinking too frequently. Blink vibrates the retinas in the eye balls, which might possibly cause serious disorders, e.g. retinal detachment or hemorrhage of the fundus for those who have too strong nearsightedness, high blood pressure or diabetes.

One of my colleagues suggested that the gradient version gives more illusion magnitude than the edge one. Then I have tried to make this work. Do you feel stronger illusion that the original? (I do not...)
