# Natural Log Fractal

Created by iterating `z' = ln(-z) / ln(z)`. I haven't seen this fractal
anywhere else, discovered it while messing around with some shader code.
Reproduced here to learn multithreading in Rust.

Usage:

```bash
git clone https://git.signorovitch.org/jacob/ln-fractal && cd ln-fractal
make
```

This will generate a series of frames zooming into the fractal (default is 50),
and link them together into a video. May take a while to run, depending on your
CPU (takes about 30s on an i9-12900K with 24 threads). The video is saved as
`output.gif`, and the frames can be viewed directly in `imgs/`.
