| For anyone who's confused about how this works: The objects

| 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.
