Yesterday I extended my little JavaScript program for the "Visualization of the Mandelbrot iteration Z=Zē+C" by the ability to plot Julia sets for given complex numbers C. If the mouse cursor is moved across the complex number plane while keeping the left mouse button pressed, the shape of the corresponding Julia set is updated "live".

Thanks FractalStefan!
The idea of visualizing the orbits is new to me, and very cool.
I plan allow the user to select an interesting starting point, and then to render the orbit and a group of neighboring orbits in a 3D stack of 2D line drawings,
and see if any interesting 3D objects result.

I've added an option to the script to colorize the exterior of the Mandelbrot set and the Julia set. It's fun to see the shapes of the Julia set changing while moving the starting point C across the plane...

I once made a similar thing in shadertoy: https://www.shadertoy.com/view/Md2cRd

Interesting, and runs very fast (compared to mine). :thumbs:
I think I should take a deeper look into WebGL which seems to be the technology behind "ShaderToy" ... :)
