I hate to see you drag in the Moon illusion on your afterimage page. I was just up
at UCSD talking to some visual physiologists, and they all agreed the standard
explanation of the Moon illusion (which you offer) is not very satisfactory, and
probably wrong. There seems to be no satisfactory explanation for that well-known
but poorly understood phenomenon. You would be better off just to delete that
paragraph from your afterimage page.
