About the challenge
BigThink × World Labs is a one-night hackathon at the University of Maryland's Iribe Center bringing together students to build with spatial AI. Using World Labs' Marble API, you'll prototype ideas at the intersection of computer vision, 3D environments, simulation, and generative worlds — then demo what you built by the end of the night.
Whether you're building a game, a scientific tool, an educational experience, or something entirely new — if it understands space, it belongs here.
Tracks: General · Best World · Best Game · Best Scientific & Engineering Application · Education · Best Video · Best Consumer Product
Team size: 1–4 people
Get started
- Form a team of 1–4 at the event (or come with one already)
- Get access to the World Labs Marble API and starter resources
Requirements
What to Build
Build any project that engages with spatial AI, 3D environments, computer vision, simulation, or generative worlds — using the World Labs Marble API. Your project should fit into at least one of the event tracks:
- General — anything that doesn't fit neatly elsewhere
- Best World — generative or interactive 3D environments
- Best Game — playable experiences with spatial mechanics
- Best Scientific & Engineering Application — tools for research, simulation, or engineering
- Education — spatial or AI-powered learning experiences
- Best Video — generated or AI-assisted video content
- Best Consumer Product — something real people would actually use
What to Submit
- Project name and description — what you built and why
- Track — which category you're competing in
- Demo link or video — a live link, screen recording, or short demo video
- GitHub repo — your code (can be private if needed)
Prizes
General
This track is open-ended and welcomes any type of project, allowing participants to explore ideas freely without constraints. It encourages creativity, experimentation, and unique concepts that may not fit into a specific category while still demonstrating strong execution.
Best World
This track focuses on building immersive and visually compelling environments that feel cohesive and engaging. Projects should emphasize spatial consistency, atmosphere, and design, creating worlds that users can explore and experience in a meaningful way.
Best Game
This track highlights interactive experiences that incorporate gameplay mechanics, objectives, or challenges. Projects should prioritize user engagement, responsiveness, and clarity, delivering a complete and enjoyable experience that users can actively participate in.
Best Scientific & Engineering Application
This track centers on practical applications that use spatial computing to model, simulate, or analyze real-world systems. Projects should demonstrate technical depth and relevance, showing how world-based approaches can support scientific discovery or engineering solutions.
Education
This track is dedicated to projects that enhance learning through interactive and spatial experiences. Submissions should focus on clarity, accessibility, and engagement, helping users better understand concepts by exploring them within a structured environment.
Best Video
This track emphasizes presentation and storytelling through video, showcasing a project’s idea, design, and experience. Projects should focus on clarity, creativity, and visual impact, effectively communicating the value of the work in a compelling format.
Best Consumer Product
This track highlights projects with real-world usability and product potential, focusing on intuitive design and clear value. Submissions should demonstrate how the idea could translate into a practical tool or experience that users would adopt in everyday contexts.
