This is weird. The decimal point is there in the message in the "sent
mail" folder, but seems to have been stripped off in the process of
transmission. (What with the speed of email and all, I guess that
little dot must have been blown right off.) The number is .675 grams.

Well, for me 5% gives too much contrast already, so I sure wouldn't
want anything less.

Well, we'll see, won't we.

Of course these wouldn't be presented like paper prints; that would
defeat the purpose, as you say. What baffles me is why you would have
supposed that anyone would do this. My idea is to sandwich them
between two pieces of glass with a frame that can be seen from both
sides, wood that holds the glass securely and provides a frame. and
then hang them between pedestals so that people can walk around
them. Kind of the way stained glass pieces are displayed.
