gsensor moves on it's own?

I'm writing a program that uses the gsensor on my HTC HD2. And for some reason the sensor seems to move, even though it's lying perfectly still on my table. When running the ball demo, the ball is rolling around without anybody touching the phone. I've calibrated the sensor with the built in calibration tool. But I still get this random movements.

Is it supposed to do this, or have I missed something?
