::I see what you mean and I agree that more information about why this fractal is notable should be added. 
 ::I do believe that this fractal is notable in its own right, we could consider merging it with the newton fractal article, but I would rather keep it separate for now if possible. Nova contains some extremely sensitive behavior that has no parallel in the newton fractal (though I am told that it is caused by a known aspect of newtons root-finding method). I have discussed this on the ultraFractal mailing list a bit. It turns out that the mandelbrot fractal formula has some similarly sensetive behavior under certain settings. I hope to elucidate this somewhat in the Mandelbrot article at some stage. 
 ::I can certainly add some information about what parameters generate the type of behavior seen in the example image, and I will also add example images that show how the fractal changes under various settings of its parameters. (I have already rendered these, and will upload them as soon as I can.)
