The particle layer is drawn with react-native-webgpu on the Dawn device that React Native Skia v3 already uses for Graphite, obtained through Skia.getNativeDevice(). Because both libraries share one device, each frame's resolve texture is wrapped as an SkImage with no copy or readback, then composited in a Skia Canvas with two blurred additive bloom passes, a star field and a powers-of-ten scale readout. The render loop is a worklet on the UI thread: it reads the Reanimated shared value set by an animated FlatList scroll handler, writes the uniforms and submits one instanced draw of 16,000 camera-facing quads, so the morph keeps pace with the finger even when the JS thread is busy. All five point clouds (four shapes plus the opening dust) are generated procedurally in TypeScript and ordered along a 3D Hilbert curve, so particle i travels a short path between shapes. The WGSL shader draws each particle as a sphere impostor that writes real depth and antialiases by writing a 4x MSAA sample mask instead of blending, so nothing is sorted. It needs a development build: Expo Go ships Skia v2, which has no Graphite device, and there is no fallback renderer, so the screen shows an error instead of the particles. Built against Expo SDK 57 and Reanimated 4. Android needs Vulkan and minSdk 26. Skia and react-native-webgpu must share a Dawn version, so upgrade them together.
An onboarding carousel where 16,000 particles morph from an atom into DNA, the Earth and a galaxy, driven directly by your swipe. The particles are rendered with WebGPU on React Native Skia's own GPU device, so the morph tracks the scroll position and can stop or reverse mid-swipe. Use it as the first-run screen of a science, education or space app.
A collapsing scroll header with a price chart, matched to X's coin page: as the feed slides over it, the header shrinks from its top edge and fades. Pull down and it rides with the content to reveal an arrow, with opacity and drift curves sampled frame by frame from a screen recording. Drop it into a crypto, stock or token detail screen.
A React Native camera screen that opens out of the Dynamic Island, then prints each shot as an instant photo that develops on screen. Pull down and the island grows into a live VisionCamera lens; press the shutter and a Skia print feeds out of a slot and comes up over a minute, faster if you shake it. Drop it into a photo or journaling app as its capture screen.
A long-press share menu matched frame by frame to Telegram: hold the share button, slide across recent chats and let go to send. The chosen avatar arcs into a toast and turns into a checkmark, with an envelope-to-bookmark variant for Saved Messages. Drop it into a chat, feed or post list that needs one-gesture sharing.
