Original author here. It only has 3 states and 6 symbols, so the transition table is not that big. If you visualized it slow enough, you might be able to understand the process behind it, so to speak. Although sometimes, simple rules can yield chaotic behavior. Someone told me they were working on a fork with utilities to visualize the transitions, that might be helpful.
That was me but so far it's just something I'd like to see. If anyone else would like to tackle it I'd be happy to watch theirs.
The general idea is a graph of the states and transitions (laid out by d3 or something?), labeled by color with little arrows for the next direction, with the current state and transition highlighted. Also a magnified 'fat bits' view of the head's neighborhood. You'd only see these at the slower speeds where you can conceivably follow, like the marker around the head in the current system.
Also you'd want single-stepping to go with this. I have added that but not pushed it to the webpage or the repo. (There was some little bug I haven't got to.)
