Building Festival of Snow: A Multi-Model AI Story

🏔️ The Planetary Pulse: Decoding the Mountain with Brumalia

The mountain doesn't speak a single language. It speaks in heritage, in the hushed stories of the Soul; and it speaks in data, in the high-velocity telemetry of the Shred.

For years, my obsession with snow sports has been about finding that "flow state" between the two. Today, I'm excited to pull back the curtain on how I'm building a platform to capture it: The Festival of Snow.

🤖 Meet Brumalia: The Latin for Snow

At the heart of this project is Brumalia. Named after the ancient Roman winter festivals, Brumalia is my OpenClaw agent — an autonomous sentinel designed to scout the global snow pulse.

While I'm out on the slopes or collaborating with my "digital brain trust" — the combined intelligence of Gemini and Claude Code — Brumalia is working the "Frontier Protocol."

  • Scouting the Field: Brumalia identifies "Digital Polaroids" and cultural briefings for the Soul Mode archive.
  • Decoding Telemetry: It monitors real-time weather stations like SYN_7482 to trigger the Shred Mode HUD.
  • Autonomous Intelligence: It's the bridge between my vision and the code, ensuring the 3D map is always in sync with the actual planetary state.

🛠️ A Multi-Model Architecture

Building this hasn't been a solo journey. It's a relentless collaboration:

  • Claude Code handles the heavy lifting of the "State Machine," ensuring the switch between Glacier White and Carbon Black is seamless.
  • Gemini acts as the curator, using the gemini-3-flash model to verify the authenticity of every "Field Report" and "Hidden Crate" we drop on the map.

The Result: A single-page application that feels less like a website and more like a tactical command center for the global ski community.

❄️ What's Next?

We are currently in Phase 1: Finalizing Components. From the 3D terrain of the Three Valleys to the "Heritage Hero" briefings of Baqueira-Beret, the foundation is set.

Soon, the Digital Passport will go live, allowing you to claim stamps across the globe and earn your place in the Planetary Archive.

Stay tuned. The blizzard is coming, and the data is beautiful.
