Everything that moves runs on the UI thread. One Reanimated shared value drives the whole screen: a single Gesture.Pan writes an offset where negative opens the lens and positive scrolls the album, with rubber banding and withDecay momentum, so there is no ScrollView. The screen is two @shopify/react-native-skia canvases, so hit testing is arithmetic in a worklet. The camera body starts as a rounded rect that matches the Dynamic Island cutout (125.33 x 36.67 pt) and grows into a 243 pt lens barrel with the react-native-vision-camera v5 preview inside it. While the print feeds out it is mapped onto a projected quad with a homography, then two critically damped springs drop it flat onto the album. One SkSL runtime effect grades every photo and doubles as development: a pale ghost that gains contrast, then colour, over 60 seconds, with noise so it comes up unevenly. useAnimatedSensor feeds the accelerometer into a useFrameCallback worklet, so shaking speeds development and swings the print like loose paper. It needs a development build, since VisionCamera v5 and Nitro modules do not run in Expo Go, and was built on Expo SDK 56 with Reanimated 4.3. The layout is designed around the iPhone Dynamic Island; on phones without one, including Android, the pill is drawn with no cutout behind it. In the iOS Simulator, which has no camera, the lens plays a looping demo reel.
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.
A horizontal gallery whose slides are wrapped around the inside of a cylinder — works squeeze hard as they roll off toward the edges while growing slightly taller, the way the inside of a partly unrolled scroll does. Drag, fling, or tap a slide that has rolled off to bring it back. Each slide is a Skia triangle mesh re-projected on the UI thread. Dressed as a small gallery archive — putty wall, numbered labels, a live catalogue counter — and hung with seven public-domain paintings, but drop it in for an editorial carousel, a product shelf, or any list that deserves more than a flat swipe.
A Dynamic Island expander: the pill morphs into a listening orb, then a spinner, then an answer card you drag down into a full-screen sheet. Reanimated shared values own every shape, Skia runtime shaders paint the light, and iOS 26 liquid glass is used when present. Drop it into an assistant, search or any app that answers from the island.
