La Ofrenda Digital — A Private, Local-AI Virtual Memorial for Día de los Muertos

Description and use

La Ofrenda Digital lets users build a virtual altar for Día de los Muertos using local Ollama models and browser storage, preserving privacy and avoiding cloud services.

Problem

People want to honor deceased loved ones with a traditional ofrenda but lack space or fear cloud AI exposing personal memories.

Outcome

The app enables a private, offline‑first virtual ofrenda that respects cultural tradition while protecting personal data.

Workflow

• Clone the GitHub repo and open index.html in a browser
• If Ollama is running, the app auto‑detects installed models via http://localhost:11434/api/tags
• Upload a photo or enter a monogram to serve as the altar centerpiece
• Select offerings such as food, incense, and personal items
• Generate a poetic tribute using a local LLM (Llama 3, Mistral, Gemma 2, Phi‑3, Qwen) via Ollama
• View the dynamic 3‑D altar with real‑time flame physics and petal particle effects
• Light virtual candles with custom dedications and a persistent vigil counter
• Listen to a procedurally synthesized 432 Hz drone and Tibetan singing bowl chimes
• Save the altar locally in localStorage for future access without cloud upload

Evidence

La Ofrenda Digital is a zero‑dependency, local‑first virtual memorial altar built for Día de los Muertos, powered by open‑weight AI running directly on your machine through Ollama.

If Ollama isn’t installed or is offline, a built‑in poetic heuristic generator seamlessly steps in so the ceremony is never interrupted.
