Thoser are pretty. How much input do you give it, and how much tweaking do you do afterwards?
I give it very little input, only a black circle somewhere on a white field. There's a few other things I can change, but I don't know what effect they will have. Then I crop it and change the coloring.
I'd like to see the source!
Well, here's pseudocode:Place a black circle randomly in a white image.Take the fourier transform of the image, creating a frequency image.Resize the frequency image, either larger or smaller, or blur it with a gaussian. This mixes up coefficients between points nearby in frequency space. It's a kind of violence, and it shakes shadows of the circle loose from itself in various uncontrolled ways, symmetric and fractal.Take an inverse Fourier transform.Adjust color map to taste.
Oh, I also sometimes shift the image (it is toroidally connected) and crop it to taste, or flip it vertically.Or I might superimpose two such pieces.I've experimented with other shapes, but I only like the results with circles.
