I never noticed this, either, until this discussion (I guess I don't
point at things....! ;-), but my experience is the same as Danny's - I
always see two fingers, neither on of which is likely to be pointed at
the subject. The left is often more solid-looking - but it does not
wind up necessarily pointed at the subject. (This may have to do with
early-on learning to be able to concentrate on more than one point in
the field of view at a time [or a part, or all of the field of view at
once]). I just assumed that anyone with binocular vision would see the
two fingers (it kinda defines binocular vision, I would think....;-).
Hope This Helps
