Something that actually connects the components and routes the traces in a way that makes it somehow still recognizable as the 3D environment would've been cool, otherwise this is kind of just like piping draw commands into a <canvas> from a hook in the Doom renderer. KiCAD just happens to be a complicated line drawing app.
Don't get me wrong, still a fun little hack. But some more PCB-ness would make it even cooler.
It might be that the website undersells it and there's more PCB-ness than I can detect in the visuals. Is it using layers and vias between them for the z-sorting or so? Both the website and the commits have a distinct AI slop feel to them and are somehow not very detailed on this part.
