Maze for stray electrons.
First idea jumping at me was some high frequency high load design.
Based on the very organic looking design, smoothly bent conductor tracks avoiding high frequency electron emitting which could ocure at sharp corners and also very heavy (over) soldering for rock solid ground and power rails.
Some elements like the srcrew terminals and uneven conductor track lengths look strange for this use case, though.
Learning its an individual build for picking up an instrument makes sense.
It looks real nice and astonishing organic
