Here is a really useful element for creating images: fractals.

What are fractals? Well, here’s what Wikipedia says (among other things): “…fractalis a term used to describe geometric shapes containing detailed structure at arbitrarily small scales.”

From that comes fractal art, which “…is a form ofalgorithmic artcreated by calculatingfractalobjects and representing the calculation results as still digital images, animations, andmedia.” There’s lots more in the Wikipedia article.

If you go to Pixabay and key in “fractal,” you will be rewarded with a wealth of shapes and patterns. Some are beautiful, like the featured image. Some are weird. Many can be combined with other design elements to produce something unique, or at least make an ordinary image interesting.
