Afterglow is a live-performance stage engine. You say a mood out loud ("make it rain") and the stage becomes it: lighting and shader change instantly, a richer scene arrives a few seconds later, and painted backdrops fade in. On-device body tracking turns your movement into neon echo trails, and what you say or sing is written above your head in handwriting that follows you. The problem: atmosphere on stage normally needs a lighting designer, a projection setup and rehearsed cues. Solo performers, streamers, teachers and small venues can't afford that, so their rooms stay flat. Afterglow lets one person direct the whole room by voice, from a browser, with nothing to install. Modes: Replace (you are cut out and placed inside the scene), Overlay (the scene is projected over your real room) and Projection (a black cut-out so real projector light skips the performer). Tap-to-try mood chips work with no microphone. Built during the hackathon: this is a new repository started during the event (Oct 26 to Nov 4, 2026); nothing pre-existed. I built it solo, using AI coding assistance. Honest limits: the live silhouette is made on-device by Google's MediaPipe, not by a Meta model, and the refined scene takes a few seconds, which is why the stage also reacts instantly to keywords.
