Today I learned that #ImageMagick has been slopped for some time. Like many tools, it's been load-bearing infrastructure for decades.

Meanwhile, the #GraphicsMagick fork has been quietly chugging along for 24 years. For most of that time, it's been maintained by a single human being.

Update: in what feels a bit like a cautionary tale, I just learned that gm also contains ai authored commits.

But wait, there's more! I also wrote a C++ program and Lua scripts to help you make animations of these higher-dimensional fractals. You can find these at https://codeberg.org/caten/RealAlgebraPlot

Not only can you see animations of the rock-paper-scissors fractal of central interest in my paper, you can also take slices of even higher-dimensional fractals coming from other real algebras, such as the octonions.

I wrote everything here from scratch as much as possible, so it has basically zero dependencies. I even opted to use Netpbm (https://en.wikipedia.org/wiki/Netpbm) so that I'd have an easy time writing image files directly without using a library. I am using #GraphicsMagick to produce animations. The same utility can be used to convert the output image files to a more familiar format like png.

Fox Squirrel (Sciurus niger) in Norman, Oklahoma, United States on May 11, 2026

Some of the camera settings I used to make this photo are at: https://www.rsok.com/~jrm/2026May31_birds_and_cats/IMG_5904c_2026may11_squirrel.html

There is also a video made from the still photo zooming in to the eye of the squirrel. https://www.rsok.com/~jrm/2026May31_birds_and_cats/video_IMG_5904c2.mp4. This has sometimes been called the "Ken Burns effect", although he was not the first to use it. https://en.wikipedia.org/wiki/Ken_Burns_effect.
