I also did one Julia animation from the perpendicular burning ship formula.
I was hoping that the amazing ifs fractals it hides in it's interior would result in an amazing animation.
But disappointingly it did not turn out so good, it looks just like static images coming out from a mirror.

I am doing these experiments with Kalles Fraktaler 0, without any high-precision. Because I have still not succeeded in render Julia with perturbation. Nothing I will make publicly available (if you don't want it very very much wink)

This is indeed not expected, as multiple fold/symmetry lines are visible. And only 1 seems to do something ... can't be right.

I've trying a bit in Gnofract4D with a custom formula. For some reason I can't use the animation director, since it complains that there would be different formulas at the keyframes (stupid program can't handle custom formulas in animatio ...?). So I rendered some frames manually and glued them into an animated GIF:

The magic seems to happend close to special points (mini's?) and it happens fast. This one is around X = -1.861576598  Y = -0.002510147. The value for Y started at -0.002510100. Gnofract4D works with size instead of zoom level. The size was 0.00023122429278918. In this direction, the special points seems to act as a seed, which generates or grows the shapes that are coming out of it. The further away, the slower the morphing process works.

Thanks youhn. Even thoug your animation is very good, I still think it is far from the standard Mandelbrot Julia, were the details are moving in all directions on every level...

Could you do a hybrid mandelbrot/burning-ship morphing julia animation ... ?  huh?

Maybe lean towards the good old Mandelbrot set, giving it 2 iterations followed by only 1 BS iteration? I think we would see some sharp folds, within smooth curves and spirals. The mset moving julia's are indeed much more beautiful and lifelike.

Here is another attempt with the Perpendicular Burning Ship, which turned out better.
The seed is going along the x-axis towards the end of the antenna:

Great. Could you describe algorithm ( how parameter c is chaning = path ) ?

Wow, that's nice! I wonder how the three seconds between 2:30 and 2:33 look like in super-slow-motion.  Spiral Thingy

z = z^2 + c, where c is slightly changed for each frame...
