Actually, I find it a little confusing, too. But actually, to get these 
three values, people only need to integrate the velocities over time, so 
maybe we don't need to provide this angle information after all.

So let's leave the gyro like it is for now, but if you have a nice idea 
how to extend the touch sensor into a pressure sensor, go for it :-)
