Modelling a mess of lines for an architectural building?

I have this architectural model to build and before I leap into it, I was wondering if you had any great ideas to make the random lines of this appear over the outer walls?

It will be for a low poly model (ie in a game environment), so I was thinking of modelling the basic shape of the walls (eg a curved box basically) and then modelling the main lines on top (with Shrinkwrap) but making the smaller lines as a transparent png. Just keeping in mind I'm trying to make this as low in poly count as possible.

Any better ideas?

Thanks in advance.

    I think your approach would probably work best, a texture with alpha transparency. Keeping it low poly as needed.
