hey, imagine if the controller had a glowing color changing LED on it. You could dim or turn off the lights and make trails with the LED while swinging away... or if it could extend a la thunder, thunder, thundercats! ha.
i'm not sure what you mean, kdr, but what i meant by directional force feedback wasn't that the analog stick would move--though that's not impossible, either. what i meant was that the remote could rotate about any axis. This is not difficult to achieve because because of an effect called counter-rotation. Helicopter propellers spin one way, and the body would spin the opposite way if not for the tail rotor... and, yes, it could and would work even on a small scale.
about force feedback for the analog stick: this is possible, too. you would simply need something on the underside of the stick (the side inside the body of the controller) in contact with it to move it. this could be achieved with to motors so there can be motion in two planes, or it can be done with piezoelectrics that would pull or push the controller in any direction.
