 played on the water. And I said, oh, God, you know, maybe the way of making this cello visually percussive is to make ripples on it, to use those ripple patterns. And people can see that, you know, yes, there are sound waves all around us, but we can't see them. But more easily translatable are water waves, which we see all the time. And so Andrew and I love that idea. And so that's how we came up with the design and the grounding of Ripple.
