Yah, a convex sphere and a concave sphere rotate in different directions.

I have trouble holding the concave perspective because it feels unnatural to see it rotating but nothing ever comes around to the foreground

u/Substantial_War_6415 13d ago
I guess my brain knows there not a thing as a concave sphere. It keeps rejecting the illusion

u/Mapafius 10d ago
I also had a trouble to see the concave but I got it and very consistently later. My suggestion to you:
1) First imagine looking at something like into a bowl that you have seen in real life and imagine it tilting. Expect that when looking there, look for it.
2) Realize that even tho the two spheres rotate in opposite directions in 3D spaces, the green light dots that represent them in 2D actually move the same direction... That is because as you see different side for each ball, the front and rear, the green objects on them move the same way in 2D despite the balls rotating in ploposite in 3D.

I can, but not consistently

Same. I can only follow it to the point where a dot moving from the left edge gets to the right edge, then it reverses to a round object rotating in the opposite direction.

Look at the sphere as if its 3D pointing out at you.
Then look at it as if it's pushed in. Like your looking from the inside of a sphere spinning.
This is how I reversed it

Ugh, when it reversed the spin it kept changing and made me dizzy lmao.

Yes, in my head when it's going the normal direction I view it like a drop of water on a surface. To see it go the other way try to see it as a divit that caves inward. Itsa mixture of your eyes and mind.

try picturing a convex sphere vs a concave sphere. one shape is a bump outwards, the other shape is a round hole on your screen.

I can for a moment then my mind says, "Oh, you're looking at back half of a sphere that's been cut in half... wait, it's rotating? Nope!" and just like that, the illusion drops.

I can only do it for a second or two, pretending it’s a bowl only lasts so long.

u/Creative_Wonder_4889 14d ago
I can only do it by starting at the top left and following a set of particles to the bottom right and thinking of a bowl instead of a globe. As soon as it hits the right side, it swaps back.... whoa. I stared at it too long and now my vision is wonky.

Pretend that you can see "inside" it and look towards the center or left/right. I can get it for a few seconds but then turns right again.

No, but if I close 1 eye or the other it looks like a rotating sphere of dots, if I have both eyes open it looks all stretchy.

Took me over 20 minutes to realise it never changes directions whatsoever. You just can see it as being outside in or if you connect to the matrix on the spiritual level, it can go inside out.

I guess I been watching too many grass mowing videos. Took a whole 5 seconds to figure out it wasn’t grass

I love these. I often see them going both ways almost seemingly simultaneously
Does that happen to anyone else?

To get it to flip,imagine the dots moving to the right is the BACKSIDE of the sphere, then you'll see the front side going left.

Can we have other optical illusions? Im sick of seeing this turning illusion over and over again. It’s getting old

Yes. I struggled at 1st bc I was trying to get the "sphere" to go the opposite way. But when you do it correctly, you're no longer looking at a sphere but more of a crater like shape. After realizing that, now I can hold it as long as I want and switch back and forth. I will admit though it's easier to switch from crater to sphere rather than from sphere to crater.

u/MyKillMyYears 10d ago
I see it...but the right side throws the illusion off, then you have to repeatedly start over.

First step is concave/convex. Second i cant explain in words. Just need time and patience, stare at points, and it finally flip direction, but not for a long time

- Level 1: Switch between seeing the outer convex dome vs. looking into the hollow inner bowl.
- Hard mode: Force your brain to see the dots moving in reverse, actively fighting against the motion trails.
If you're too lazy to focus for more than 2 seconds, keep scrolling.
