This is a new one I saw on Brain games the other night and had never seen before.

Look at the yellow dot, which way do the balls rotate, look at the red, they should switch.

You can also mess around with the speed by looking at different areas of the orange. It slows down as you look to the edges, speeds up when you look between the two rings of dots. You can almost get the dots to stop orbiting but they they still spin.

Neat. Now stare at the spot between them, and try to see them both spinning in their true direction (both counterclockwise.)

I'm so wasted.

I suspect this has to do with the distribution of cones and rods in the retina.
Your center of vision (acuity) is via the cones, while night and peripheral vision is via the rods.
The cones see color and refresh rapidly, while the rods see b/w and are slower to refresh.

If you do that then ever so slightly move your eyes to your right, you can reverse the rotation to clockwise.

Looking about 2:00 from the red dot is the closest I can get to stopping the spin on both sides.

What does this mean? After some excellent Viognier and a Black Russian, I don't know, but I'm sure it's significant.

Like, whoaahh ....


There is a conflict generated in our brains by the use of black and white stripes in the moving dots. The dots are moving at one pace, and I think the stripes actually move within the dots, thereby suggesting a different pace. Both paces are represented in our brains. We flick from one interpretation to another.

There may even be a third interpretation as our brains interpret the dots as holes in a moving screen and the stripes as being the background seen through them, generating a third rate of movement to "perceive".


Seriously, like, whooah.

Man, that's a good one.
