This is a submission for the Hacktoberfest Open-Source AI Challenge Week 4: Ghost in the Machine
"There are three deaths in this world:
The first is when our body ceases to breathe.
The second is when they lower us into the earth.
And the third, the true and final death, is when no one speaks our name again."
— Traditional Mexican Adage
Between the twilight of Halloween on October 31 and the sacred dawn of Día de los Muertos (Day of the Dead) on November 1 and 2, ancient folklore tells us that the veil separating the living from the departed wears thin. Across Mexico and throughout homes worldwide, families assemble ofrendas—multi-tiered altars illuminated by flickering candlelight (velas), draped in golden marigolds (cempasúchil), and adorned with favorite foods, portraits, and memories of those who have crossed over.
For the "Ghost in the Machine" challenge, I built Ofrenda Viva ("Living Offering"): an interactive, audio-visual digital memorial sanctuary and local AI spirit oracle. It allows anyone to pay homage to the legendary computing pioneers whose ideas literally live inside our hardware and software, or build an air-gapped memorial altar for their own departed family members, mentors, and beloved pets.

Ghost in the Machine — Día de los Muertos & Open-Source AI Challenge Submission
A 100% private, air-gapped memorial altar powered by client-side open-weight models, procedural Web Audio synthesis, and real-time marigold petal physics.
Ofrenda Viva ("Living Offering") is a digital sanctuary honoring Día de los Muertos (Day of the Dead) and Halloween, built on a fundamental principle: Grief, ancestral memory, and intimate human eulogies belong solely to the individual, never to centralized corporate surveillance clouds.
In traditional Mexican heritage, an ofrenda is a sacred three-tiered altar created to welcome back the souls of loved ones on November 1st and 2nd. The veil between past and present thins, guided by glowing candles (velas), the golden scent of marigolds (cempasúchil), fragrant copal incense, and heartfelt memories.
Ofrenda Viva brings this tradition into the…
