I’ve spent months building a three.js frontend that turns a Jellyfin library into a first-person 1990s video store. Real floor plan, genre aisles, a clerk who recommends from what you actually own, a checkout ritual with a shiny bag. It runs 24/7 on our family’s HTPC as the actual way we pick movies.

Just made it public under GPL-3.0.

Stack: Vite + TypeScript + three.js, optional Tauri wrapper (mpv playback, HDMI-CEC), optional Jellyseerr and RomM integrations, plus a pure HTML/CSS 2.5D mode for weak hardware.
