The human brain is hardwired for taking shortcuts, making assumptions, pattern recognition especially of familiar objects, including living things--animals. faces. This is what makes optical illusions work, and how we end up with geological features named 'ship rock', 'turtle rock'. It's also the why behind people thinking they see Jesus or his mother Mary in the browning patterns on toasted bread or water stained walls. What do you see in the photos below, if anything?
Here's a wider shot, which gives a clue as to what is forming the 'illusion'. Let me be clear here...i attach no significance to what i see in these photos, it's just an interesting phenomena. However, that does not mean i automatically dismiss things others see in odd places or the significance they may attach to what they see. But i'm usually full of questions and collect evidence pro/con whatever they submit to me.
