This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Shadows do generally overrepresent the color blue due to rayleigh scattering.
Brains are also very quick to make assumptions and also very rigid about keeping them. The spinning dancer illusion, even when you already know you can and have seen it spinning both ways, it can be difficult to switch percepts.
I get the illusion with the blue radiograph halfway down, but I've never been able to easily switch the dancer.
Sometimes I can and sometimes I can't. When I looked this up earlier, I was able to switch twice. But yeah, if I'm just staring at it, it's basically impossible.
I switched the first time because I looked at the reflection underneath the dancer, and that seemed to remove just enough visual context that I could reorient my perception.
