Hi SkwareUawe,
Great minds think alike! I’ve actually done work on implementing Langton’s Ant in VCV Rack as my first Rack module. Finding this post has inspired me to re-engage with the project. In all honesty it has been gathering dust for the last six months. 
Also, good call PaulPiko! I actually lifted parts of Jeremy Wen’s NoteSeq for this project (with attribution of course). Below is a screenshot of early development. I’m calling it Aunty Langton’s Musical Ant.
I’ve actually got a video catpure of it in action too. I’ll add a link to a youtube vid shortly.
Thanks for spurring me back into action on this! The implementation is mostly complete, at least for a first release. Now to properly design the panel so it’s not so goddamn ugly 
Here’s that vid: Musical Ant - Mystical Ant Patch
Cheers!
