I would have sworn that was from a fractal generator, incredible how often fractals show up in nature

Agreed, looks like a Mandelbrot zoom image or perhaps a Julia (I hope I spelled his name correctly) set.

Also looks like ice freezing on my window the last days

so fractals don't just show up in nature! Fractals were created In Order to better capture nature! tbs, the traditional mathematics was proving insufficient for the first geographic maps on digital displays - that are zoomable (like your Google maps today) so they had to come up with fractal mathematics for that..🤷‍♀️

Ah I don't think that's true, Mandelbrot created the first one experimenting with recursion whole working at IBM. It proved very useful in mapping complex objects that seemed like they had no mathematical basis later?
