I just went to the New Scientist site
http://www.newscientist.com/inprint/previous/20011124.jsp
but the article is not e-accessable.
as katlaughing put it - it is a visualization process but the article adds scientific weight - 14% in fact.
I can scan and e-mail as jpg if you PM me here.

thanks for folks condolences. It was Sept that May died and was relatively easy for me as I had done plenty to help her over the years and there were no loose ends, no regrets, "job done" as it were.
Mind you she was there when my name was invented (no not Red) so the friendship went back longer than I do!!!
