Beautiful fractal. I always see in the abstract images everyday objects, like people, tools and flowers. This one looks to me like a special decorative cabbage I tried once to grow in my garden, with little success since the dogs ate it... But its a beautiful pot plant and your fractal looks just like it.
Question: Is there a reason why you make your image so large? Except for the fact that the rendering takes a long time, do you get a better quality making it large? Or perhaps it is needed if you want to make a print out of it??
