The moving tunnel effect:

I find it more intense if you shift your eyes back and forth from the upper left to the middle to lower right.

* A circle of purple spots, one spot disappears clockwise.
    * A circle of purple spots, one spot turns green clockwise.
    * THE GREEN SPOT EATS THE PURPLE ONES !.
    * Only the green spot remains, circling around the cross.

If you have trouble with this illusion, view it with one eye closed or covered.

Could these sculptures really exist?

Click the spoiler for the answer AFTER looking at them.

[spoiler]No, they are impossible figures, they can be drawn on paper but not constructed. [/spoiler]

Is it supposed to give the effect of moving? Nothing happened when I looked at the pic?  I started at it from different angles, different areas and tried to look at "out of focuts" for lack of a better expression?  What am I not doing right?

Yes, it should look like the dots are rolling along on a belt..try looking from the center black area to the lower right, then back to center, but stay in focus.

Ok I tried again and noticed a barely perceptible impression of it moving.  Thing is if I blinked I could miss it....maybe my eyes are messed up?

You just may not be as sensitive to it. I don't think there's anything wrong with your eyes.

Straight- or not straight?

After you take a good look at it, lay a straight edge such as a ruler or piece of paper along each side.

That tunnel one is weird. I would not want to look at that while high on drugs.
