For anyone who's confused about where to find the images: Click "Figures" in the sidebar on the right.

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.

This page presents Sugihara’s earlier work and provides 360 degree view:

What sidebar? I don't see a sidebar. When I click the figures the site just hijacks my browser history.

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.

You need to hold your phone up to a mirror to see it.
If I force desktop view on mobile the sidebar appears
Rotating phone to landscape worked for me.

Desktop mode showed me the same content on my device.

Thank you! Here's a link: https://journalofillusion.net/index.php/joi/article/view/983...

I suppose it only works on camera. I can't imagine it works in person.
It works only from the forced perspective angle. If you move the camera, the image morphs.
The article has a whole section "Robustness against changes in viewpoint" where it argues that it's good.
Also you have to hold your phone sideways to see the sidebar.
