Wow this is kind of a new one for me!

You can scribe out a motion path and get that to be fairly intricate.  The only thing I can think of is to put a particle generator on a motion path.

Set the particle generator to generate particles in a VERY ordered fashion and use metaballs for the particles.

Then have the particle generator flow along the path and "create" the cable as it goes.

Have the "end" of the cable follow the same path.

This is just a whackazoid idea sitting here thinking about it for two minutes but that's what I'd try.
