Show HN: I built a new version of my fun spatial 3D online meeting app Hi HN! flat.social is a fun spatial online meeting app for remote teams and communities. It's largely built like a web multiplayer game, and the 3D virtual spaces are highly customisable with elements and activities (I recently added surfing!). Live demo to try it out: https://bit.ly/4cQRNth Here's a quick demo video: https://www.youtube.com/watch?v=GeinBNqL23s It's a solo, bootstrapped project built with Three.js, LiveKit and Rapier for physics. I built the first version during the pandemic and posted it here back then: https://bit.ly/3xN9kNJ I had a couple of months off this year, so I locked myself in an (almost) jungle house in Brazil and rebuilt it into what I've always wanted it to be. Would love to hear what you think! https://bit.ly/3xHUoAw September 17, 2026 at 01:57PM
