[Widget suggestion] Gyroscope

I would love to be able to control my robot by tilting my phone.
This would imply a widget similar to joystick, with 3 output pin (3 axis, each axis of phone’s rotation, x, y , z, https://developer.apple.com/library/ios/documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/Art/gyro_rotation_2x.png).
