Personality disorder green ring of light?

Hey guys, I was just playing some Amped 3 a couple of seconds ago, and noticed in the corner of my eye that my green ring of light seemed to be flickering. So I stared at it for a moment, and noticed that the portion that shows where the first controller is, would change from that section of the ring, to the section where the second controller should be. So to sum it up, I had no other controllers being turned on, quadrant 1 would immediatley swap over to quadrant 2, and after a few seconds, go back to quadrant 1.

Anyone else ever had this happen to them, or know what it means?

The blinking green light is not distracting. The true gamer must learn to master his environment and be able to accept a sudden change. He must be one with his controller and his console. He must beleieve in himself and his ability to game. A simple flickering green light shall not destroy the true gamers power!!!!!!!!!!!!!!

I think I had the same problem and I have a pretty good idea of what causes it. The 360 knows if it's lying flat or on its side, and the lights rotate to reflect which position it's in. The blinking light is caused by the 360 getting confused about what side it's on. Mine is usually on its side, so I turned it flat, then turned it back. I haven't seen the same problem since.
