Hi all!
This is *Golubaja, founder of , giving her contribute to the Fractal Week... gnarls!
I'm quite sure gnarl is my favourite fractal style, I love making gnarls both in Apophysis and in UltraFractal. But first of all...

What is gnarl?

Verb
Infinitive: to gnarl
Third person singular: gnarls
Simple past: gnarled
Past participle: gnarled

1. (transitive) to knot or twist something
2. (intransitive) to snarl or growl; to gnar

Noun
Singular: gnarl
Plural: gnarls

1. a knot in wood; a large or hard knot, or a protuberance with twisted grain, on a tree.
2. something resembling a knot in wood, such as in stone or limbs.
3. (mathematics) The average value of the magnitude squared of the curl of a vector field over a continuous path that is tangent to the vector field at every point. In mathematical notation, gnarl is represented by the lowercase Greek letter ξ.

Translated into Fractal Art, gnarl becomes many things: formulas, coloring algorithms, mappings, variations and variables... Combining shapes, gradients, weights, colors and transparency on gnarls is like opening your eyes on an unexpected, amazing, constantly renewing multiverse.
In a single word: awesomeness.

Learning gnarl style is not so difficult, and making gnarls will give you the strongest emotions and the greatest satisfaction.

Where to start from? Let's have a look!

In Apophysis:

here are some basic gnarl params to play with, copy and paste them directly into Apophysis and have fun!
Remember: the secret for Apo gnarls is Waves2 plugin and its variables, together with the weight of the related X-form and the values of Xaos.
These params make a just two X-forms Apo flame; try and add a Final X-form, play with it and you'll get amazing results!

Here are some Apo gnarls with params to tweak:

In Ultra Fractal:

here are some very basic gnarl params, involving just one of the many gnarl formulas that you can find in UF.
Try and change the formula parameters to get started, then try and add layers, change formulas, play with gradients... It will be awesome!

Here are some UF gnarls with params to tweak:

And now, a collection of the best gnarls ever on dA.
It was very, very hard to choose!

Thank you very much for adding an image of mine to your article! I really appreciate it! Without features like yours, I don't think anyone would even bother to look in my corner of the art world.
