MindAttune
Read full descriptionHide full description
MindAttune is a generative artwork for iPhone and iPad — a field of soft, luminous voices that drift endlessly in and out of alignment and never play the same moment twice. Nine sustained tones, each tuned to a calming frequency and given its own slow loop of a slightly different length, are set running together. Because no two loops share a common cycle, the voices slide forever against one another — gathering into chords that bloom, dissolve, and never quite recur. Always different, always the same. Watch bands of warm-to-cool light swell and fade. Turn on the sound and the same system becomes audible: an ever-shifting ambient drone you can sink into. Then simply leave it running — as a focus aid, a calm corner of your day, or something to drift off to. Every frame is generated live on your device. Nothing is pre-recorded and nothing loops; what you see and hear right now has never existed before and won't return. Features A living generative field — never the same twice Ambient sound tuned to nine calming (Solfeggio) frequencies, driven by the same drifting clock as the visuals Hands-on controls: voices, drift rate, sound-to-silence balance, incommensurability, bloom, sway, and a custom color palette Seeded compositions — find a configuration you love and return to any time Immersive full-screen mode Plays through the speaker, earphones, or external speakers Runs entirely offline Plant a few seeds, set the conditions, and watch what grows.
