Built with react-native-reanimated v4 and react-native-worklets. A useAnimatedScrollHandler keeps the live scroll offset in a shared value, and each item interpolates that offset on the UI thread: translateY follows a circular arc (Math.sin(PI/4) for the off-center points), while opacity, scale, and a blurRadius animated prop on Animated.Image make the centered item pop and the edges recede. Snapping uses pagingEnabled + snapToInterval, and selection haptics fire via expo-haptics through runOnJS so the JS-thread call never blocks the worklet. Tested on Expo SDK 56 (RN 0.85, New Architecture). The animated blurRadius renders more smoothly on iOS than Android; transparent source PNGs keep the blur following the artwork rather than a hard rectangle.
A horizontal carousel that glides its items along a circular arc as you scroll, scaling up the centered item while its neighbors shrink, fade, and blur. It snaps to each item with selection haptics and drives a synced detail card. Drop it into ride pickers, category selectors, or product showcases.
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.
