A simple script to render typst and make animations. Checkout https://github.com/liquidhelium/tanim for a simlilar program that does the same thing. (spoiler: it is less flexible in terms of data flow but it runs much faster)

1. Download the required assets via ./download_assets.sh.
2. Render the animation via ./tanim.sh. You can run the script with --help to see more details.

Note that sometimes you might want to specify the --cookies argument in case if YouTube blocks you from downloading the audio. All the dependencies are listed out in <./shell.nix>.
