Wicked Cool Monochrome Fractals

For secret reasons I have needed a large number of very big fractal images in black and white only, detailed but not too detailed, and kind of tentacle-looking. Y'know the sort of thing that could be cut out as its own standalone design and appear somewhere creepy to freak people out. I am probably not up to anything bad. 

I couldn't find any that worked for what I needed so I made some, and then I was possessed by something terrible and rendered out ten of them in fuckoff huge* sizes.

*Anywhere from 8k to 16k. You can zoom in pretty far! Alas you cannot zoom in forever, as these are only pictures of fractals and not real live ones.
