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.
Accessibility would be too accessible. For extra fun, make the scrolls bars reversed and inverted axises. After all, it's not like there are disabled people who use assistive devices need simpler, properly-designed websites. Also, it's not GDPR compliant and demands acceptance of cookies.
That is awesome. I can't wait to see the STL files people make so we can all print them up!
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.
The linked STL is a different Kokichi Sugihara illusion - by the same creator as this new class of illusions, and part of a body of work in this field that this appears to be a continuation of.
But it is. Those are objects that are mirror symmetric, and the apparent direction they're facing depends on viewing angle, creating the illusion that they haven't actually been mirrored.
The apparent failure to mirror "correctly" left and right in this illusion reminds me of a great interview question I heard: why does a mirror reverse things left and right, but not flip them top and bottom?
It can be fun to watch people scratch their head over it.
Are you implying _two_ eyes? Because if you think that's the reason, just try closing one eye and looking into a mirror and you'll see that nothing's changed.
(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?
