Ah, I should have read post 2 and 3 more carefully! It's making more sense to me now. I find the results are better for zoomed-in sections, since, with black borders, the highlights tend to sink into the border junctions in the main shapes and interrupt the illusion of shape a little bit. But on the edges, I now have nice balloon-like structures, just as I had hoped to!

One thing I noticed is that I had initially misread part of your formula, but gotten similar results... You highlight the cell edges with "min/min2", while I set mine up based on "min2 - min".
I suppose it's a similar idea either way. with yours, value approaches 1 when the distances are the same, and with mine, value approaches 0.

Anyway, here's an example of today's tinkering after your hint.

Update: I like your method better (min/min2) It does a much better job of scaling the intensity for areas that show higher-iteration details.

There is no right or wrong version. Dividing sort of scales wall thickness with cell size; while subtraction sort of sets a constant boundary thickness. Either may be more appropriate for any given image. I think of it as a design decision.

BTW, one welcome side effect of me being a bit vague (about computing final colors from the raw values) is that some of you might discover yet more interesting variants that would have never occurred to me.
