Show HN: I built a new version of my fun spatial 3D online meeting app
Introducing flat.social: A New Era of Absurdly Delightful Online Meetings
Welcome to flat.social, a platform designed to transform the way we connect digitally. Instead of being trapped in a static interface, you can now create a playful virtual environment where guests move, interact, and socialize naturally—all directly within their web browser.
🚀 The Core Experience
Forget the boring grid of tiny rectangles. flat.social reimagines the online meeting as a creative playground, blending the functionality of a professional tool with the mechanics of a multiplayer game.
Key Capabilities
- Virtual Hangouts: Navigate a 3D space, bump into colleagues, and engage in organic conversations.
- Spatial Audio: Experience sound that mimics reality. The volume adjusts based on proximity:
- Interactive Fun: Break the ice with built-in games and bonding activities.
- Deep Collaboration: Work side-by-side using shared whiteboards and collaborative tools.
- Professional Events: Host structured webinars and conferences featuring Q&A sessions and screen sharing.
- Total Customization: Tailor your environment with bespoke maps, specific room layouts, and corporate branding.

🛠️ How it Works: The Spatial Logic
Unlike traditional software, flat.social uses a spatial movement system to dictate social interaction.
