Living Stage

Living Stage is a presentation surface that builds itself while you talk. The presenter speaks into a mic or types a short phrase, and an interactive visualization grows on screen in real time. At the center sits a hands-on mathematical model with sliders the speaker can drag mid-sentence. The chart behind the slider re-evaluates at 60 frames per second on a hand-drawn canvas, so the audience sees the model react instead of staring at a static image. Around the hero, supporting widgets like time series charts, side-by-side comparisons, flow diagrams, and annotated formulas with rendered math appear phrase by phrase as the talk unfolds. Follow-up phrases add to the existing scene rather than replacing it, so the slide is literally growing while you speak. If the speaker says, “forget that, now show something else,” the stage resets cleanly. The problem it solves is the gap between rehearsed static slides and the live conversation in the room. Conventional decks are assembled days before the talk and cannot respond once the talk starts. Living Stage removes the deck entirely and gives the audience something the speaker can actually manipulate. It runs on Gemini 3.5 Flash through the official SDK, with streaming structured JSON, a byte-stable prompt prefix that hits the implicit cache, and an honest fallback that announces itself if anything in the live path takes longer than four seconds.
