About the Project

The rope is a chain of point masses solved with time-corrected Verlet integration and a Gauss-Seidel relaxation pass for distance constraints. Both run inside a Reanimated worklet driven by a withRepeat ticker, so the simulation and Skia path rebuild happen entirely on the UI thread. The pan gesture pins the lamp during drag and converts release velocity into Verlet displacement so the rope keeps its momentum. Built against Expo SDK 54 with Skia, Reanimated, Gesture Handler, expo-av, and expo-haptics. Works on both iOS and Android; no custom native code.

Lamp Rope

$10

Legendaryreanimatedexporeact native skiareact native gesture handlerreact native

An interactive lamp dangling from a physics-simulated rope. Drag the lamp around with a pan gesture and pull it past a threshold to trigger a haptic, a sound, and a flickering light cone. Drop it into an onboarding screen, an empty state, or a playful settings toggle.

Receipt Printer

Receipt Printer

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.

Telegram Swipe Actions

Telegram Swipe Actions

A Telegram-style chat list row you can drag either way to reveal circular action buttons — Mute, Delete, Archive on the left drag, Unread and Pin on the right. Buttons stagger in as the row travels, overdragging stretches the edge button into a pill that fires its action on release, and only one row can ever be open at a time. Drop it around any list item (FlatList, LegendList, FlashList) that needs iOS-grade swipe actions.

Flip Calendar

An Apple-Calendar-style card whose big day number split-flaps through dates like an airport board or flip clock. Every flip is driven by a single 0..1 shared value, so you can scrub it with the included drag slider or play it through with a spring or timing the control and the calendar can never disagree.

Still circling? Snatch it.

Most crows would've grabbed something by now.
