Zoom into Julia set for -0.390625 - 1.015625i for variation on secant formula composed with Mandelbox variant:

in Java lambdas (variable & method names should be self-explanatory, but if anyone wants more details please message me :)):

(z, c) -> z.minus((z.minus(zPrevious).over(z.pow(powerOfZ).minus(zPrevious.squared()).times(z.squared()))));

composed with

(z, c) -> z.boxFold(0.5).ballFold(0.5, 1.0).times(mBoxScale).plus(c);

I think mBoxScale was set to -1.5; see the Mandelbox info on these fora re the ballfold and boxfold transforms and scale factor.
