I don't know, the copy I have was sent to me by Alan K IIRC, and the 
only other person who did host it was David Wilkinson who is no longer
with us, I havn't seen Sam around in a while and feel a bit reluctant
to host it all things being considered. 

I'll send it right over Tom. 

If Sam's reading and doesn't mind someone hosting the tutorial then let
me know and I'll put it up somewhere along with a zipped copy that people
can d/l.

I think Bob Hughes hosted it for some time but i don't know if it's still
available on his web site.

No, he wanted it offline because he felt it got too outdated.

I got a mail from Samuel, he would be grateful if you host his tutorial
although he thinks it is somewhat outdated. 

It would probably be good to mention on the tutorial starting page that
the descriptions refer to the megapov implementation of isosurfaces and
that there are some differences to POV-Ray 3.5.
