the wire plugin from the post above is exactly what you're looking for. the inner wires in the image you spoke of aren't
textures they are geometry, you just have to think non-linear. make a curve, make into wire w/o adding a profile, make as 3 wires, then make each of those three a wire again as 2 wires, the sets of 2 will wrap around each other and all 3 sets will wrap aswell, now it's just the matter that the demo is pretty limited. have fun. post some pics when you're done
