Here’s how to make animations like this one. It requires intermediate Unix command-line knowledge, to install some tools and to debug if they don’t work. You’ll need these utilities:
curl (or you can translate to wget)convert and montage, part of ImageMagickffmpeg, plus whatever codecsparallel, for iteration that’s nicer than shell for loops or xargszsh for leading 0s in numerical ranges to work
