Over the last few months I have created a file of unique Newton, Halley, and Householder method formulas, and would like to upload them to the public database. Rather than include them with my previously existing formula files, since there are so many entires I would like to create a jam-Newton.ufm file or something like that. Who do I contact these days about creating a new formula file for th

Does anyone know how to write a formula for this fractal?
I've seen it called a teardrop or mandeldrop fractal, but after much experimentation have been unable to recreate it.

There may already be a formula for this in the database, but I couldn't find one.

This is a formula I found initially through a program for the iPad called Frax...
They use a Line Average coloring algorithm... I googled it and found this.
I have no clue how to program it into UF, so I was hoping to find someone here that did know how...

float xmin = -2.5;
float ymin = -2.0;
float wh = 4;
float stripes = 5.0;
int maxIterations = 1000;

void setup() {

Hi.
is it possible to provide the option of alternative bailouts in the same formula?

More specifically, I wanted to include convergent and divergent bailouts:
|z|<@bailout (default 4.0)
|z|>@bailout (default 0.001)
It seems only one expression is allowed in the bailout section. Is there a way to do this? Any help would be appreciated.
