I tried phone, similar. I guess it kind of does keep rotating, but you can’t see it. Colors fade faster than flow. If you dab a finger in the stream at right angles to the flow you made, the splash flows the expected way, but maybe slower than water. It would be good to visualize any flow. And also to respond to device orientation so you can feed the resonance :)
