He gets us!

Lol at the car on background

or the hand anatomy of those girls.
- Is the girl in blue holding two cups or the other girl able to bend in freakishly awkward ways?

The word you're looking for is squint

This is honestly one of the genuinely really unique good use cases for AI art generation, I think

I love it that the next comment down is "AI was a mistake"
Totally not a gimmick.
It's a pretty good case for photo editing programs too if you look at the hand anatomy and the car in the background and basically any other detail in the work

That car in the back looks tippy as fuck, like slamming the breaks would smash the front bumper on the ground

Ok It it's AI generated but I want to know what's happening at the cognitive level. This is unlike other multistable images I've seen before. Can someone explain how this works brain-wise?

Since birth our brains are wired to look for faces. It helps with survival when the helpless wiggly thing bonds with the giant who is full of hormones telling them to protect it.
As we grow we learn to recognize other patterns, which help us find food, be safe, find a mate, etc. Our brains are constantly looking to match everything we see with something from a previous experience. Which is unfortunately one of the places PTSD can pop up. Say you had a traumatic experience - you may not remember seeing someone wearing a red hat just prior to something terrible happening, but your brain might. In the aftermath it's possible that you find yourself uncomfortable around someone wearing a red hat but can't figure out why. You may not remember, but your brain does and thinks it's helping by alerting you too a problem.
You ever been barely awake and see a coat on a chair and jump cus your brain says there’s a dude standing there? It’s that.
- Ah ye, I can relate the the effects. Thanks
