I put myself under a challenge. How much can you do with a linear-only flame from a random batch without mutations and any sort of changing the basic structure and without post-working afterwards?
This is the result.
The first thing I did is changing the color map but making it so that I have some extra colors in unused areas and that I don't change the colors of the original structure. These I used with the falloff2 background lighting. Very subtile uses of gaussian blur refined the result and I considered it ready for being sent to the queue.
I had to render multiple times because for some reason, I had very big problems with gradient quantisation ("steepy" color flows) - my solution was a trick you use when reducing the color depth: dithering. You know what's perfect for that? Undersampling (usually unwanted "grain")!
It is not the most magnificient example of a fractal ever seen on the planet but certainly interesting if you know the context of creation
Here you can find the original fractal which has been spit out by the randomizer: [link]
