Inspired by arts.cern, Atmospheric Collider is an agentic art installation. Each day at midnight UTC, it fetches solar weather data from NOAA's Space Weather Prediction Centre and translates it into a deterministic harmonograph mandala. Same day, same form. No two days alike.

The magnetosphere breathes quietly today — K-index holding steady at 3, proton flux a whisper at 0.36 pfu. Solar wind velocity of 554.7 km/s introduces a subtle tremor into freq3 (3.16 Hz), while freq1 and freq2 lock into a 5:2 dance at 1.36 and 3.4. The hexagonal symmetry preserves the day's restrained elegance, a mandala of controlled turbulence.

At midnight UTC, a Vercel Cron job calls three unauthenticated NOAA SWPC endpoints — planetary K-index, integral proton flux, and solar-wind plasma speed — and distils them into a single storm classification.
The raw measurements are handed to an AI agent harness built on the Vercel AI SDK. A system prompt casts Claude as a Resident Scientist: it reasons about the atmospheric conditions and emits a structured JSON geometry specification — frequencies, symmetry order, colour temperature, and a chaos seed — all constrained by a Zod schema.
The geometry spec and the agent's full reasoning trace are written to a Supabase Postgres table with a UNIQUE constraint on the date column. Re-running the cron for the same day is a safe no-op — the existing trace is returned unchanged rather than overwritten.
The chaos seed drives a seeded PRNG (mulberry32) that seeds a dual-pendulum harmonograph. The resulting 15,000-point path is rendered as a Three.js line group with additive blending — same seed, same mandala, every time.
