Well, say you have some sort of power house... futuristic type. On one side have the machinery that is producing the electricity, be it pumps, flowing etc that give off a redish glow, well maybe the pumps and such dont have to give off the glow but you get the point. Then on the other side have power cupplings that give off a blueish glow to show that the power generator is working and such and for the links in between.. have wires running through it as if it were a connector... which it is
