Here I deal with the edges by having them fade away. The “mountains” are due to a programming error. I’m used to doing colors in RGB coordinates (red-green-blue) where I can blend two colors by taking a simple average. Here I’m using HSV coordinates (hue-saturation-value). Saturation and value can be averaged, but hue is a circular coordinate. It’s like trying to average East and West… is the answer North or South? Both or neither?
I think the crystallization works better in HSV, so now I blend by converting to RGB, averaging, and converting back to HSV. Lots of number crunching, lots of conversion formulas to learn, and a few accidental mountains to look at.
