Scientific explanation (in understandable language) anyone?
That is amazing.
Brain fooled again! Do you know you spend four hours of your waking time blind? Look in a mirror, look at your left eye, then your right? Can you see your eyes move? You can't, the reason being that when you move your eyes to look somewhere else, the signal from the eye to the brain are blanked out. This is stop you getting motion sickness as you would see a view like that on a rolling ship.
I love it, my dad used to have a postcard with a similar sort of picture on it. It fascinated us kids and kept us quiet for hours !!
That is so weird, but good.
