Now I'll point out a trick. You seem pretty clever, so maybe you know it already. But you didn't use it, so here we go.

Suppose you make a function that uses V - i.e. it evolves in the vertical dimension, as you have done many times now. Suppose this we know this function confines it's most interesting work where 0 <= V <= .5, i.e. it does nothing interesting when .5 < V.

Now let's define a variable like this (the name is a clue):

symV = Min(V, 1-V)

And you replace all occurences of V in your function with symV.

What do you get?

This is one of my favorite tricks. How much of your church pillar goes away? How many nodes disappear?

For this really advanced stuff, reducing node count can be the most fun part of the effort.

I hope you don't mind the challenges. I'm enjoying the fact that I seem to have a kindred spirit.
