You can try gEDA topological autorouter Toporouter: https://youtu.be/NqT4ZYGB3VY

You can also use TopoR autorouter for free: https://en.wikipedia.org/wiki/TopoR

Topological routers make really interesting board designs looking like something retro or biological in its nature :)

I did try TopoR back in the day, but the lack of integrations was IIRC a PITN.

I've not tried Toporouter and will go paly with it, thanks for the pointer.
