Musée Du Monde

Built during World Labs’ first in-person hackathon in San Francisco (February 2026), Musée Du Monde is an interactive 3D museum experience that lets users step inside paintings and explore them from the artist’s perspective.

Created by Ankur Jain, Jake Kang, and Vatsal Bajaj, the project was the winning submission of the event.

The Experience

Inspired by films like Midnight in Paris, the project transforms iconic artworks into explorable Gaussian splat environments connected through a central museum hub.

• Walk through paintings in realtime
• Portal-based transitions between worlds
• Desktop and mobile spatial exploration

The experience begins inside a Marble-generated museum space, where each painting acts as a gateway into a different immersive world.

How It Works

Each artwork is processed through Marble to generate an explorable Gaussian splat scene. Those scenes are then connected together using Three.js and SparkJS inside a browser-based portal system.

As users approach a painting, the destination world begins streaming in dynamically. Walking through the portal crossfades between scenes, creating seamless transitions between the museum and each painting world.

Stack

• Marble for painting-to-world generation
• SparkJS + Three.js for splat rendering and portals
• Vanilla JavaScript + Vite for the web experience
• Vercel for deployment and hosting

What’s Next

• Interactive storybook experiences generated scene-by-scene
• Expanded cinematic transitions between worlds
• More immersive approaches to spatial storytelling through art
