BTW did you visit back to the thread I started in the Bryce forum and see what David had added to it.
I’ve been back a couple of times to check the progress of the thread. While the effect is interesting (as explained so far) I think it’s a little limiting for what I want to achieve. I’ll keep poking my head in over the next couple of days and see what comes of it. In the meantime, I’m still considering my options…
