Auctually the ones I have seen you will find on our main web site.
http://spaceandmotion.com/
and a large number of other links and info. I would have to ask Geoff, but I believe the main website has over 150 pages, and every page is good sized. Average time spent per page about half an hour if you look at it all, so he has a search feature to help. So I do agree with many of the links you gave.
P.S. Geoff Haselhurst is also lives in Australia and a few other members of our forum.
