InkWall transforms static links into a collaborative, living canvas. Built originally as a dynamic E-Ink surface for my GitHub README, it acts as a Global Public Billboard across the entire web. Whenever you share the InkWall link on platforms that support Open Graph previews—like Discord, Slack, X, Telegram, or Threads—it displays a live, server-rendered SVG of the latest public submission. When a visitor publishes a new note or drawing, every previously shared preview updates automatically. One link. Infinite, real-time updates. ✨ What makes it special: Global Link Billboard: A crowd-sourced, dynamic Open Graph surface that turns a simple URL into an ever-changing public ad space or community canvas. Smart Client-Side Processing: The browser editor handles cropping, zooming, inversion, and compression into a compact four-tone WebP locally before anything touches the server. True Privacy-First Architecture: No external analytics SDKs, no raw IP logging, and no browser fingerprinting. Visitors are correlated strictly via temporary, server-side HMAC hashes. Modular & Robust Moderation: Features automated review pipelines (supporting OpenAI, DeepSeek, or local Ollama models) with seamless fallbacks to manual human review, ensuring the live surface stays clean without breaking the render. Lightweight & Fast: 100% hand-crafted with a PHP/SQLite backend that generates responsive, theme-aware SVGs on the fly—zero build steps or GitHub Actions required.
