Cellular automaton snowflake generator

I made a simple cellular automaton snowflake generator in OpenSCAD. By default it uses Stephen Wolfram's rule that a hex cell stays alive once alive and a cell is generated if it has exactly one neighbor.

Christmas Day addition:
Adding a tiny bit of indeterminism--a chance of 0.5 of generating a cell instead of certainty--makes things look more like a real snowflake, though. Tap on Customizer in the above link if you want to play with it.
And here it is on our Christmas tree. Merry Christmas!

Dr. Pruss, I'm sorry that this is off topic, but do you think Edward Feser's work in Natural Theology is cogent? In particular, his new book Five Proofs of the Existence of God presents arguments from Aquinas, Leibniz, Aristotle, and other classical philosophers.

I was hoping especially to hear your thoughts on his formulation of an Aristotelian "unmoved-mover" argument which eventually proceeds from the analysis of change as the actualization of a potential and the premise that change--so understood--requires a "changer" to the conclusion that there is an Unactualized Actualizer of the existence of the "hierarchical" series of changes. Is this truly a defensible and cogent argument for the existence of God, by your judgement?
