PS I appreciate the background observations; still, I like very much the way you have handled the subject as a vignette (OK maybe we should start a new thread...)

I think that you have very successfully integrated the figure with the ground, much more difficult that it might seem at first blush.

For those who drop in, I have known Richard for quite a long time, and he has been very focused on excellence in his work. I know that he puts in many hours, and seeks out excellent teachers.

Richard, it really shows.
