LOL…the fractal eggheads compile the code and offer them up for grabs. Once you download them into your scripts directory you can call them up to run them. What many script n00bs do is start tinkering with the numbers in the code to see how each affects the flame. After a while you begin to develop an understanding of the formulas and how to use them in combinations with others and develop your own script. There is a script manual floating out there somewhere for those who want to dabble. But scripting is not necessary since you can continue pressing ctrl+B to churn out new flames until you see something you like. When you do you can then mutate the flame , edit its attractors, change its color gradient and so on. After you’ve developed your masterpiece you can then render it out as an overlay where the entire background color is missing and you only have the flame. You can then bring it to an image editor and go to town on it…lots of fun really.
