Fascinating optical illusions.

One half of my brain can't be working properly? - but I've been told that, on occasions. 

[Jerry_Atrick]

Don't worry OT, my brain also defaults to upside down stairs.. and I have been accused of not even having a brain! 🙂

IF it's not a  MRI operator I'd ignore it. IF they find "normal brain Atrophy" you don't get any Trophy, either. Nev

A few  little trickies in  there.. If you're colour blind it might be a bigger problem. Nev

Doctor! My eyes! - to quote Jackson Browne.

I'm not colourblind, but I couldn't make out anything in that.

For most people the lines start bending.

Ah, yes I saw that, but Nev's post made me think there must have been more detail.

Did anyone see an elephant?

[nomadpete]

No elephants in my room!

 

On my little screen, the peripheral lines bent a lot. But my wife just saw straight ones.

You guys are smarter than me tho....  i can still only see the lower halves of naked women in the first pic. Yes, I did try to see something else.

Hey, the pro hart comment helped....  now I can see some real skinny guys with their arms held up high.

The background is what distorts the Grid you see first. (If you look at it correctly.. Your MIND is responsible for trying to make it make sense. It often "fills in" things for you whether you want it to or not. (Bit like spell check).   I'm NOT saying I have seen ALL but the grid is normal.  There's a thing called astigmatism some people have which bends straight lines. Try a test for that. (Google it Mate). Nev

I went back and looke, then it clicked, but still must need a tonne of therapy🙄

Maybe you have a special clairvoyance. There's a fine line between genius and insanity. (according to some) Nev

Here is an interesting site (well to me at least) that allows you to dial in different parameters to the curved grid illusion.  The most interesting one is that the grey cobble stone squares only work in one orientation, rotate just a little them and the illusion immediately disappears.
