Very Cool little app
Just randomly bought and played around with this, and as a sound designer / (visual) artist, plus someone who’s fascinated with physics, including quantum mechanics, which this absolutely relates to in terms of fields of probability, this is great. A couple features I’d really love to see in addition to the mic input suggested in another comment, would be to feed Audio Unit app sound into it, or at least be able to choose from some other basic waveforms (i.e.: pure sine, triangle, saw, and square waves - ideally with pulse width modification as a bonus). That could really elevate the reusability of the app. Also being a software/web developer as a day job, I could see expanding this in plenty of other fun ways, like color gradients/themes for the digital “sand” particles here, and so on. Anyway, great work so far and hats off - hope this continues to be developed!
