rolling-number

Rolling Number is a TypeScript library for interruptible, locale-aware rolling numbers on the web, with a framework-independent DOM API and optional React and Solid adapters. It formats values with native Intl.NumberFormat, animates bounded digit reels using native browser animation playback and sampled critically damped spring easing, and samples the current position and velocity when an update interrupts an animation rather than restarting from the old target. It also provides RollingText for direct glyph transitions, alphabet-wheel animation, and split-flap displays. React and Solid adapters keep readable formatted text separate from decorative animated glyphs, while reduced-motion, unsupported formats, and offscreen states retain static text for accessibility; decorative glyphs are hidden from assistive technology. The DOM core has no runtime dependencies and the project is MIT licensed.

Bang Motion is an agent skill for building browser-based motion graphics such as product openers, promos, bumpers, channel intros, kinetic typography, lower thirds, and explainers. It produces a single index.html that plays in a browser and encodes anti-slide rules: scenes change through camera or world movement rather than section fades, subjects or shared worlds persist, motion occurs continuously, and text and numbers remain part of the scene. Its deterministic timeline makes each frame a pure function of time for exact scrubbing and frame-by-frame export, while a shared camera rig supports flowing-world and camera-through-collage modes. The skill includes five explainer starters—cartoon collage, visual journalism, white catalog, vintage sketch, and continuous action—along with configurable style briefs, background motion, surfaces, transitions, highlight shapes, voice-over re-timing, and optional Puppeteer and FFmpeg scripts for verification and MP4 export. It can be installed as a Claude Code plugin or copied into Claude Code, Codex CLI, Gemini CLI, Cursor, or another agent workflow; watching the output requires only a browser and internet connection. The repository is licensed under MIT.

Remocn is a copy-paste component library for building videos with Remotion. It provides animations, transitions, backgrounds, scenes, fades, wipes, and kinetic titles as Remotion code that developers add to their projects through the shadcn component registry and can modify directly. Its components use Remotion's `useCurrentFrame()`, `interpolate()`, and `spring()` APIs. Component pages provide live previews using `@remotion/player`, allowing frame-by-frame scrubbing. Remotion is required as a prerequisite, and the project also provides an optional agent skill for setting up and working on Remotion video projects.

kugiri is a text-preparation library for animation that splits text into lines, words, and characters exactly where the browser has already wrapped it. It measures browser wrapping to preserve layouts such as balanced headings and vertical text while exposing individual text elements to animation tools.

OpenSlides is a free, open-source offline desktop application for creating animated code presentations. It turns source code into slides and converts selected lines into presentation steps, using Magic Move transitions to animate changes between code states and stepped highlights with configurable dimming, scaling, and transition timing. It provides light and dark themes, 16 syntax themes, slide search, thumbnails, keyboard navigation, full-screen playback, optional autoplay with per-slide timing, and project operations such as duplication, import, export, and drag-and-drop reordering. Built with Tauri and Svelte 5, it keeps projects on the local computer and provides installers for macOS, Windows, and Linux.
