Very nice image, and I agree with you on the light, but I'd make it go
even further out, since it is not a very good comparison wiht the
lighthouse and the length of the beam..

Can you please post with all images as attachments, and with only plain
text when you send ?
There has been much argumants about this erlier, and several of the
people on the newsgroup has readers that don't support html, or pay by
the minute, and therefore is put at an disadvangtage when you post like
this..
