Hey Kaz!

Guys you're miles ahead of me, I'm still learning.
Must study your reply more but 'linear' is sticking in my mind.
There is something to that as well as your left/right examples
that I can not yet articulate (its frustrating to recognize
these patterns but lack the vocabulary to describe them - argh!).

At any rate thanks Kaz.
