The original Strange Zone set was published in 2021. It arose from work I was doing with fractals. The underlying formulas were very complex. In was not something any sane mathematician would study.

The functions involved complex exponentiation, which is a multi-valued (in fact infinitely valued) function. So there is a “pick one” step that creates effects that do not happen with well-behaved functions.

The present series tries to resurrect the feeling of the original. But with the techniques of my recent work, rather than strange fractal formulas.
