Lumen-Sonic

Built at Gemini 3 Paris Hackathon · Mar 14, 2026

Demo video · github.com/…

Lumen-Sonic turns any light source into an original music track. Point your phone at a lamp, candle, or neon sign — Gemini 3 Vision analyzes the light's color temperature, flicker rate, and brightness arc, then writes a music prompt. Lyria generates a 30-second WAV file from that prompt. No two lights sound the same, and the same light can sound different on different phones due to sensor and white-balance variance.
