So my girlfriend loves her Nora, but she likes the vibration part a little better than the motion.  When we sync Max and Nora, it isn't clear how the movements drive one another.  Clearly the Max has to physically move to make Nora do something.  You can't, for example, hold the Max against a wall and pump into it because that stops Nora from moving.  So, you have to slide Max around to get Nora to move - but how do I move Max to make Nora's vibrator work as opposed to making the shaft part move?   Just curious for tips here...
