Fascinating article, I can't wait to read more. Kind of makes me think of my grandpa. He sees things backwards and upside down. He was not able to read until the age of 50. It took him many years to just understand why he was not seeing things the same as others.
yes this is more neurological, for some sees everything upside down because of an abnormal connection in the way their brain processes images. Some say its dyslexia (which is a mental illness). But to me if he is normal in each and every way except the way he sees then it is something more Neurological.
Interesting, thanks for the input.
