A few initial states of game 0000343234320000111 have been removed.

The program that “digests” the seed is here. (It is still to be updated with the Beggar-my-neighbour generator...)


The video was produced via Feedpovray. Each part renders a different set of permutation numbers.

The video fragments were created with ffmpeg:

    ffmpeg -framerate 23.976 -pattern_type glob -i '*.png' -i "$1" \
           -c:a aac -b:a 128k  -c:v libx264 -r 23.976 -pix_fmt yuv420p \
           -filter:v "fade=in:st=0:d=5, fade=out:st=$duration:d=5" video.mp4

where “$1” is the audio data.

Finally, I concatenated the videos and added chapters, also via ffmpeg.
