Original Summary

Hi HN!<p>flat.social is a fun spatial online meeting app for remote teams and communities. It&#x27;s largely built like a web multiplayer game, and the 3D virtual spaces are highly customisable with elements and activities (I recently added surfing!).<p>Live demo to try it out: <a href="https:&#x2F;&#x2F;app.flat.social&#x2F;f&#x2F;demo-flat" rel="nofollow">https:&#x2F;&#x2F;app.flat.social&#x2F;f&#x2F;demo-flat</a><p>Here&#x27;s a quick demo video: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=GeinBNqL23s" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=GeinBNqL23s</a><p>It&#x27;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: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=31833415">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=31833415</a><p>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&#x27;ve always wanted it to be.<p>Would love to hear what you think!
