Right hand dominant, and feeding the resonance with either hand feels fairly easy, I feel the wave coming and responding to it comes naturally. I do try to use my left hand every so often, but I wouldn't say I'm ambidextrous. In general, I find that my left hand is not very good at adjusting how much force is needed for fine movements, so for more complex tasks than swirling water the level of control is pretty rough. I can browse the web, code, or do other basic activities with the mouse in my left hand, but I wouldn't try to play videogames with it for example (and let's not talk about my handwriting!).
