A few hops away, the non-mathematical part of this story is interesting[0] and Conway's related weird world of audio-active decay is another recurring favorite[1]. Both are even more fun with esolangs[2]. I'm sure I've heard audio-encodings of Kolakoski before, but couldn't find any with a quick search
