Thanks, for all the replies.
The thread in March wasn't the one because I remembered it as being within the
last three months so it was probably that from August, but what Peter has here
should keep me happy for a while.
BTW: I'm truly very sorry that I can't show you what this is all about, since
it's a project I'm working on that is now close to 200Mb. Just let me say that
it is great fun and nearly 100% POV-Ray on the outside 8)
