Tripothon S1 World-Building Demo Day @ Barcelona
📍 Barcelona, Spain
Carrer dels Ferrers, 11, Sant Martí, 08019 Barcelona, Spain
Hosted by Tripo AI
Barcelona, what world would you create as a gift? 🌍✨
Tripothon S1, Tripo AI’s free global AI × 3D world-building hackathon, is coming to Barcelona on October 17 — with a total global prize pool of US$80,000.
This season’s theme is: A Gift for ____
Build a world as a gift — for your younger self, your future self, a friend eight time zones away, a stray cat on the corner, someone having a hard time, the aliens about to arrive, or even the dark side of the moon.
Your world can be big or small: a breathing city, a memory you can walk into, a game, a planet that existed for only six hours, or an interactive experience no one has seen before.
The only standard is simple: when your world is unveiled, someone should want to stay and explore it.
Tripothon brings together creators from around the world across AI, 3D, games, XR, digital art, interactive experiences, and physical creation.
On October 17, selected teams will come together in Barcelona to present what they’ve built, meet fellow creators, connect with judges and industry experts, and compete for Tripothon awards.
What you’ll find:
🎮 Playable worlds, games & interactive experiences
🌍 AI-powered 3D world-building projects
🖼️ Digital art, XR, visual experiments & creative technology
🤝 Creators, students, developers, artists, educators & industry professionals
🏆 Live project presentations and Tripothon awards
✨ A full day of ideas, experiments, and worlds worth stepping into
