Playing with fractal generators can result in images that remind some of creatures in the natural world. Did you know that the nudibranch^ can be evocative of certain Julia-set fractals? Especially when you see them in motion. Be sure to check out the "scubadiving" and related YouTube tags for other deep-sea creatures. I especially liked this one.
What are nudibranchs? Jewels of the sea. Page after page of photographs of these squishy hermaphrodites.
