This is where I am indexing my Mandelbrot images and other fractal images. I am currently using Xaos to render the images. The coordinates of each Mandelbrot is stored in the metadata of its PNG file, which can be viewed with programs such as the Gnome Image Viewer. The links below follow the gemfeed format in case you wish to subscribe within a gemini client.
For the theological significance of fractals, please see Dr. Jason Lisle's book "Fractals: The Secret Code of Creation" (ISBN-10: 1683442407).
