this looks really like when -thousands of years ago- I was very fascinated by Voronoi diagrams
in my case it was a terrible mix of:
messing up with cell offset + not even being aware those curves had overlapped start/end control points, swearing all the time why the cells always had a sharp corner somewhere
mix it up with a non uniform XY scaling, and this goes straight back into my drawer of dark memories that should not be remembered
