A flat-vector space explainer drawn entirely in code: narration-timed camera moves, counters and a tiny mascot.

What it does

A 30-second "what if" explainer in flat-vector style (a navy starfield, a shader-lit Earth with city lights, a small astronaut mascot, and countdowns and labels that fire on the narrator's words, such as "8:20 until Earth notices") drawn entirely in code, with no AI images or video. Finn rebuilt the look of a famous science channel with Opus 5.5 and gave away the whole prompt: one HTML file where every frame is a pure function of time, ElevenLabs narration with word timestamps, and Playwright seeking every frame. An agent writes the narration with one visual event per key word, gets timestamps from ElevenLabs v4 (or Whisper), builds canvas and WebGL scenes as a HyperFrames composition, and mixes a music bed and per-event SFX.

Status

A format people ask for that has no dedicated skill yet. Make it with the skills on the use-case pages below, or with varg directly.

Example: https://x.com/finnardley/status/2114305886420086817

How an agent would make it: Topic → narration with one visual event per key word → ElevenLabs v4 voice with timestamps → code-drawn 2D canvas + WebGL globe scenes, every frame a pure function of time → HyperFrames render → music bed + SFX, mastered to -14 LUFS

Models it drives: eleven_v4, whisper, render
