A pixel-accurate recreation of the shimmering dot placeholder ChatGPT shows while generating an image: a static grid of dots lit by invisible orbs that take turns blooming, drifting, and dissolving across the card. Ships with the cycling typewriter status label ("Sketching it out", "Polishing details"…) so you can drop a complete generating-state card into any AI or long-running-task screen.
The whole animation is a pure function of time, so there is no integration state and nothing to desync. A Reanimated useFrameCallback worklet samples 2 orbs per frame (position from a Catmull-Rom spline through golden-angle waypoints, brightness from a raised-cosine pulse envelope), and a useRSXformBuffer mapper rewrites every dot's transform on the UI thread — React never re-renders after mount. Skia draws the entire grid in one Atlas/drawAtlas call against a single mipmapped circle sprite, so a 25x40 grid costs one draw, not a thousand views. Timings (4.6s pulse period, Gaussian falloff exp(-5.15r²/R²), ±0.26 bloom offset) were measured frame-by-frame off screen recordings of the real app. Built on Expo SDK 56, Reanimated 4 and @shopify/react-native-skia 2.6 — Skia is native, so it needs a development build rather than Expo Go; on web the CanvasKit WASM must be loaded before render, which the included loadSkiaWeb.web.ts handles. Identical output on iOS and Android; the iOS-only TopBar/Composer variants degrade to plain translucent views elsewhere via platform extensions.
A Telegram-style capture button whose microphone glyph morphs into a video camera on tap, with a springy pop under the finger and a liquid-glass circular surface. Every stroke is interpolated on the UI thread, so the mic cradle rises into the camera housing and the capsule head rounds into a lens in one continuous outline. Drop it into a chat composer, a recorder screen, or anywhere you need an audio/video capture toggle.
A pixel-matched recreation of Telegram's attachment menu: the paperclip button in the input bar morphs into a full liquid-glass bottom sheet, then drags between detents or flicks away to dismiss. Ships eight cross-faded panes (photo grid, text, file, location, poll, checklist, audio, contact) behind a scrolling native UISegmentedControl. Drop it into any RN/Expo chat screen that needs a real attachment picker.
A complete voice-assistant listening screen: a Skia orb that swells, fattens and ripples in time with whatever the microphone hears. Raw PCM is split into low, mid and high bands and pushed into Reanimated shared values, so the whole animation runs on the UI thread and React never re-renders while you talk. Drop it in as an AI-assistant, voice-note or call screen.
