i thought so as well, but after the drydock tests with the nunchuck in my hand or lying on my desktop i had to see that this whole matter is getting somewhat spoiled. I dont know about 'real' nunchucks, as this one is a 12$ imitation from china. It is good for playing, but the overall accel sensor output is extremely noisy. When lying flat on the desk i have quite some noisy ouput. Then again a ssecond problem was that lousy box, the chuck was able to move in it any way it wanted, so i could never get the real G forces as i had some fatigue movement on the chuck itself..
It was just that - a small experiment out of massive boredom ;0)
