Multitouch.inputMode = MultitouchInputMode.GESTURE;
logo.addEventListener(TransformGestureEvent.GESTURE_ROTATE, onRotate );
logo.addEventListener(TransformGestureEvent.GESTURE_ZOOM, onZoom );
}

// pssst... you should try rotationX or Y
logo.rotation += evt.rotation;
}
private function onZoom(evt:TransformGestureEvent):void
{
logo.scaleX *= evt.scaleX;
