Orientation

I have created an application that draws the a rotating line according to the orientation of my accelerometer. It works very well on at least the X axis however it is easy to fool by shaking it violently. This can be corrected by a waiting period, if I am upside down for a certain length of time then I am definitely upside. Self built in latency is not a great thing to have. Better the accuracy than the latency. I will try to program the Y axis next to provide more of a stable relationship.
