Is It Possible to Make a Retractable Lightning?

Aluminium would fit with Apple's other products, which it should be anyway. I think they could put a nice clip on it. So people could clip it into their pockets more than anything. And something that I would really like to see them do in a very elegant way is a retractable lightning plug or whatever you'd call it. If there's one thing we know about Apple is that they hate moving parts.
