Fans of OPTICAL illusions are going crazy over this bizarre photo, but not everyone can see what’s hidden inside.
This is not your everyday stone wall.

A clever trick contains something else if you look closely.
Magiceye0, who shared the clip, explains how to unlock the secret.
“Hold the screen close to your eyes and slowly zoom out until a 3D image appears,” they explain.
It may not work the first time, so be prepared to try several times.
And some people can’t get it to work at all, so you may need to see if a friend or family member can reveal the hidden image for you.
If you’re ready to give up, we can find out what it is.
The hidden object is a triceratops dinosaur.
A clever illusion is actually known as an autostereogram.
Some know it as the Magic Eye, after a series of books on the trick.
It works by tricking our eyes and brain into seeing a three-dimensional scene within a two-dimensional image.
At first, you’ll see a bunch of 2D patterns over and over again.
This is because our brain automatically tells our eyes to focus on the image.
But by looking beyond the obvious and focusing behind the 2D pattern, your eyes begin to see things from a different angle.
It is at this point that the hidden image is revealed, when something called stereopsis kicks in, allowing your brain to construct a 3D image instead of a 2D one.
The idea started as stereograms, which a scientist named Charles Wheatstone discovered in 1838 by combining mirrors and lenses to create the first stereoscope.
The autostereogram arose after him, in the 1970s, thanks to another scientist, Christopher Tyler, who used computers to create the kind of optical illusions we see above.
If you want to try more, there are other autostereogram tricks.
This one is hiding something among a bunch of emoji faces.
There is also another rain theme worth trying.
