intersect . . . invisible images

[Richmond Mathewson]

I hope his shin does; unless, of course, his transparency level is below 
a certain threshold.

The problem is NOT the invisible man; it's the kid he fathered on a 
visible woman so we
have the 50% visible child, also known as "The situation that H.G.Wells 
didn't think about too
carefully."

Things get even more difficult in further generation with the 5% visible 
descendant,
the 95% visible distant cousin and so forth.
