Thank you very much Paolo!

I was a bit worried that it might be only me that liked it.

This image reminds me of turbofan jet engine fan blades.

No, no... me too of course;)
Very good job.

I don't have too much time right now, but I'm continuing my research.

Thank you Kurtz. I'm glad to hear that !

That's yet another function with nice domain colors. It seems that you have a
talent for finding such functions.

Are your functions related for some physics related project that you are working
on ?

When you mention it; yes I agree.

And that would be a nice and colorful engine  ;-)

May be, may be ... but i don't do it deliberately ;)

Here a new field of investigation z = f(f(z)).
with f(z) = cos(z) / sin(z^4-1)
Found on <https://www.jedsoft.org/fun/complex/index.html>

Not at all. It's just for fun and the beauty of mathematics.

That's a nice image. With your coloring it looks better than the one John has on
that page.

I see. At the moment it's the same for me.
