IMVVVHO, an interesting IFS:
Here is a IFS I created/(discovered?) for an "infinite"
forest setting. A rendering of the formula can be found
here:

Where `rn' is a random number from 0...1:
_________________________________________
if (rn < 0.0108)
{
px = px - tan(px) + (cos(px) / 2.0);
py = py + abs(cos(px * 1.618));
}
else if (rn < 0.068)
{
px = cos(px - 0.01);
py = sin(py + 0.4);
}
else
{
px = cos(px + 0.6);
py = sin(py / 1.168);
}
_________________________________________
Is this worth a flying shi%?

Thanks... :^)
FWIW, I am in the process of animating this thing. Basically
create a fractal explorer program for non-linear IFS. I guess,
this is a fractal flame. AFAICT, and to my eye, the IFS does create
a pleasant forest setting with trees, mountain ranges, sine paths
within and pine cones...
