As I wrote about KPT Bryce in July 2023, there are image generating programs that use fractal geometry instead of artificial intelligence (AI).
Another such image generator program is Evolvotron. It can generate fractal-based images with different patterns, colors, and shapes.
It has an interactive interface driven by user choices in response to a field of different images–each generated from a different set of parameters. Based on this initial field of images, the user can choose File > Reset (or press R on the keyboard) to generate a new field of images.
When one of these images is one that the user likes or would like to explore more, they can right click and choose to Respawn (just the one square), Spawn (generate images with adjacent parameters), Spawn recoloured (same originating parameters but different colors), and other functions such as Spawn warped (below), Enlarge (below), and Save.
Below are a few images at 1024 x 1024 that I generated with Evolvotron.
I installed Evolvotron from the Debian 12 repositories. It can also be downloaded for various Linux distributions here, and it is available for MacOS X via Fink.
