(minor critique/complaint) It would be a touch cleaner if you moved the orbital lua script into the main folder of your github project, rather than have it nested down one level
If I grab this with git clone, I will see the script showing up in the norns SELECT menu as orbital/p1505/orbital and orbital/p1505/src/orbital_circle
If orbital_circle is a library, place it in a lib folder and then it wont get listed in the select menu.
