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.
The paperclip button and the expanded sheet are literally the same view: a single Reanimated shared value interpolates left/top/width/height and four corner radii from button frame to sheet frame, while the contents are laid out once at full size and uniformly scaled, so nothing reflows mid-flight. Spring parameters (duration 320, dampingRatio 0.83) and the backdrop's separate decelerating curve were derived frame-by-frame from a screen recording, and every layout number in theme.ts is expressed as a ratio of a 402x874pt viewport so it holds on other devices. A pan gesture on the header drives the sheet's top edge with overshoot resistance and snaps to a detent on release, or dismisses on velocity. Panes stay mounted after first visit and cross-fade, preserving scroll position and typed text. Built on Expo SDK 56, RN 0.85, Reanimated 4 with react-native-worklets, and React Compiler. iOS-first: the segmented control is a real UISegmentedControl in a Swift Expo module (it scrolls its own segments — a RN ScrollView can't, the control eats the drag), and expo-glass-effect provides the liquid glass with a white-wash fallback where it's unavailable. One iOS quirk is handled explicitly: a UIVisualEffectView installs its effect on first layout only, so the menu bar's glass is remounted via a key once the sheet has settled open. Requires a dev build — the native module means this does not run in Expo Go.
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.
A full-screen rain overlay where thousands of depth-sorted drops fall past your UI and splash on the cards they hit, styled after the Apple Weather app. Drop the RainOverlay over any screen, feed it the rects you want rain to collide with, and it renders the entire storm on the GPU.
The iPhone Dynamic Island morphs into a thermal printer and feeds out a receipt line-block by line-block, then tap to tear the finished sheet away. Perfect for checkout confirmations, order-success screens, paywalls, or any moment worth celebrating.
