A cable pattern is like a set of serpentine or wave-like cables, each one meandering around its own center line. A vast variety of cable patterns can be invented by changing the number of cables, the separations of their center lines, the amplitudes of their waves (i.e., how far they wander from their center line), the shape of the waves (e.g., sinusoidal versus triangular), and the relative position of the crests and troughs of each wave (e.g., one wave crests as another is crossing its center line).
