I can see I didn't express myself very well if _that's_ what you think
I was suggesting!  8-)  Bear with me and let me try again.  No doubt I've
violated the law of requisite complexity once more.  8-)

OK, let's say you got a white object at some distance.  It images once
through the red side and once through the blue side of the lens.  So 
you get a white object with a red ghost on one side of it and a blue ghost 
on the other.  If the white object had been at a different distance, the
ghosts would have gained or lost weight.  Now when you go to view this
image, you won't see the two images in the same place; they will be dispaced 
from each other.

OK, now we go to a black object.  Oops!  Aha!  Now I see why it works.  8*)
You still get the fringes.  They're not of the object but of its background.
But that doesn't matter; it still works.  Did I geddit?  Did I?  Did I?

I don't understand either and I've been trying a _long_ time.  Maybe this
penance thing will work.  Nothing else has.  8-(  Now how does it go again?
