I'm now ready to start setting up a more satisfactory demo version with some interesting action, so I'll be working in Povray a lot - a condition that isn't conducive to much reporting from me.
I'd like again to appeal to anyone who wants to collaborate on the Povray side. I'd be delighted to share the load and the credit with you.
Meanwhile, and this is the problem with me, I've seen another possible use of the Jade engine and I keep thinking about that instead of getting on with what I should be doing!
