Sacred Drift is a living field of light you keep in your pocket. Open the app and a slow-breathing cloud of bioluminescent particles fills your screen. Drag to orbit, pinch to zoom in. Tap the dice for a fresh field — every roll is a unique scene, never the same twice. Tap the heart when you find one you love and it's saved as a "recipe": a tiny shareable file that reproduces the exact look on any device, including any web browser. Built on a custom physics engine running 60 frames a second, Sacred Drift is an entire generative art studio that fits in a button row: • 5 motion modes — drift, plus four classic strange attractors (Lorenz, Aizawa, Thomas, Halvorsen) • 4 confinement shapes — particles can swirl through a torus, an N-sided polygon tube, a logarithmic galaxy spiral, or a star tetrahedron (merkaba) • 22 hand-curated palettes from infrared to aurora to chlorophyll • 19 starting presets — Astrophage, Plasma Storm, Aurora Drift, Deep Cosmos, Embers, Stardust, Lorenz Wing, Spiral Galaxy, Merkaba Star and more — or roll the dice • 5 spawn distributions: uniform, central focus, hollow shell, diagonal, twin clusters • Soft-edged additive blending with HDR bloom + vignette • Trail persistence for long-exposure ribbons of light • Optional repulsor for negative-space compositions • Camera auto-orbit • Snapshot the current frame to your photo library — with or without a transparent background • Recipe import / export — share scenes with anyone Privacy: Sacred Drift makes zero network calls. There is no account, no analytics, no advertising, no data collected. Everything happens locally on your phone. Sister app: Sacred Spin (mandalas you spin and tune) is also available.
