Even if there is some photoshop going on there, what I was seeing was totally surreal. If you follow the instructions and watch the center cross the faces become like Salvador Dali paintings or weird cartoon caricatures.

Our brains (or at least my brain) just doesn't have quite enough time to process each face before it changes to the next one, which creates a weird effect where the faces don't look real.

I was making screen caps of the images I thought were photoshopped, but the screen caps loooked normal.

It is a weird phenomena.

As suggested on Nyarl's link, the effect persists even if you hide one of the two faces (but still center your gaze on the cross). One of the comments was "overclocking the visual cortex"! :D

Yep. Kinda confusing though because when you look at one the others seem to disappear.

Shit happens. The older you get, the more often shit happens. So you have to try not to give a shit even when you do. Because, if you give too many shits, you've created your own shit creek and there's no way out other than swimming through the shit. Oh, and fuck.

Best new one I've seen in a long time.

Can be spinning left or right.

Once your brain locks onto one direction, it's really hard to switch to the other. Try closing your left eye and right eye back and forth. You'll eventually see both.
Such potential!

I wonder if a person would look odd walking past that area, because our brain is using the floor for visual cues on relative size and distance.
"If fighting is sure to result in victory, then you must fight! Sun Tzu said that, and I'd say he knows a little bit more about fighting than you do, pal, because he invented it, and then he perfected it so that no living man could best him in the ring of honor. Then, he used his fight money to buy two of every animal on earth, and then he herded them onto a boat, and then he beat the crap out of every single one. And from that day forward any time a bunch of animals are together in one place it's called a zoo! (Beat) Unless it's a farm!"

That was a fad sorta thing back in the 17th 18th century. The artist would paint the image using a mirror.
