Take a look at this picture and what do you
see? You think it’s just a brick wall, right?
And you might also see a turtle’s head between the cracks. At first glance it appears we are looking
at a normal wall with a simple small rock embedded between two of the red bricks. If you said turtle’s head, you’re close
but no cigar, I’m afraid. And it’s not a lump of rock. There’s way more to it than
you think. But the image has gone viral as people have
spotted a hidden optical illusion of something emerging from the wall.
