Very very nice ))
u/tzador

Could you explain how you achieve this wayve gradient pattern?
u/rodrigo.siqueira

About the horizontal lines around the circle: u/tzador, in your original code if you change Y=...%9-4 for Y=.../400-4 then you will see parallel horizontal lines around the circle in middle. In my case, the lines around appear by using %1 here w=...+Y*Y%1
u/rodrigo.siqueira

About the gradient: It's given here by using "Y" values to pixel size (w). if you change to w=.4/Z+Y then you will see a strong and simple "Y" gradient. If you try w=.4/Z+X then you will see vertical instead of horizontal gradient. Then the %1 will "break the gradient" in multiple gradients of "width 1"
u/tzador

Thank you, will try it out in the next one ))

Logistics map with some bifurcation, still trying to figure out how to make it look pretty tho

u/artfarnaa

Nice, though I suggest provide a link to background info on what a logistics map is and what bifurcation does. We newbies need just a tad of hand holding.
