Double-mirror illusion

For anyone who's confused about how this works: The objects aren't what they appear to be from any angle. In fact, they're weird mirror symmetric objects that bend backwards in ways you wouldn't expect. It's our shape recognition that makes them look flatter than they are. This also makes them look like asymmetric objects that are facing a certain direction depending on the viewing angle, and this is the actual illusion.
It's sad that we don't get a 360 degree view, or even a couple of rotations of one of these, because that would make it obvious that the object goes from "proper shape" to "unrecognizable shape" to "flipped shape" depending on angle.
Anyway, when viewed in the mirror from certain angles, first of all the object doesn't change (because it's mirror symmetric). But because you view the mirror image from a different angle, it looks as if it's facing the other direction.
I think it's about time companies hire the mentally challenged to be front-end devs. I commend the site for breaking new ground in equity.

Thank you! Here's a link: https://journalofillusion.net/index.php/joi/article/view/983...
The left-hand scrollbar controls and reports on the left-hand viewport. The right-hand scrollbar the right-hand viewport.
More conventional organisation (and less confusing, possibly) would be to retain the scrollbars to the right of the corresponding viewport.
Note that left-handed scrollbars are occasionally used elsewhere, as in the X11 Athena Widgets (Xaw) set:
Why can't most websites stick to the basics. Sigh!
I can't imagine what is so unique in presenting this article or this site's content that it requires so much of custom non-standard trickery.
Meanwhile, here is a single mirror illusion STL file and a video showing off how similar illusions work https://www.thingiverse.com/thing:1970522 You can play with the STL in 3D and get a bit of an idea of how it works.
It can be fun to watch people scratch their head over it.
(Also, as an exception to your statement, I have eyes, and I wasn't able to grasp why it happens until I watched a video about it.)

Are these special objects? Which figures in the article are thoe being displayed in?
To me, each example basically "works" if you pretend its not a mirror corner but just a solid mirror at an angle. I'm guessing this is not the intent though?
