Semi OT: Twitching Mac pointer

Has anyone ever seen a pointer on a Mac start to twitch? Mine seems to have started jiggleing back and forth slightly. Really disconcerting. Any ideas on if this is the mouse, or the machine :^( It seems to have something to do with how the cord is twisted, so I'm suspecting that the wires are getting a little frayed :^( When I smooth the cable out, it seems to stop.
