What if Tech Week wasn’t a calendar, but a city you could actually enter and play?

We made a SF TECH WEEK CITY — rebuilding San Francisco as a 3D world with Tech Week events placed at their real venues.

RSVP activity, trending events, and busy areas become part of the world itself. The birds flying above the city represent real community members, so you can see where people are heading and explore alongside them.

Built with AI coding and published on Chrona.

A small experiment in turning real-world data into a place worth entering.

Time to ship a playable world

[mr.bruce @chrona01]

SF Tech Week (@Techweek_) just broke its own record — 1,500+ events, the biggest Tech Week ever. So which ones have the most RSVPs, and which are actually worth your time?

We vibe-coded SF TECH WEEK CITY: a multiplayer 3D world with San Francisco rebuilt 1:1 and every event at its real venue. Not single-player, not a static map — it's live, synced to Tech Week in real time: RSVP counts, trending events, the busiest blocks. Every bird in the sky is a real person on X, so you can see who's heading where and fly with them.

This world is a preview of our own SF Tech Week event 👇

🎮 Meshy × Chrona: Build Multiplayer 3D Worlds With AI — Chrona's official launch, co-hosted with @MeshyAI. Live multiplayer world demos, fireside chats, and more playable, interactive worlds to try on site.
📅 Saturday, October 10 | 1:30–6:00 PM PT
📍 Downtown SF (exact location shared on RSVP)
Sponsored by Seedance · #SFTechWeek

On going list: gaming & entertainment investors from around the world, plus people from Roblox, Epic Games, world-model labs and film/TV. Seats are limited — if it overflows, we'll move to a bigger venue.

Come as a guest, or bring a world as a creator. Creators who join get token rewards from @MeshyAI — and a bigger surprise for the ones who make it onto the live demo stage.

@JimmyZh0523 wow that's so cool

[mr.bruce @chrona01]

最近CodexやClaude Code、Seedanceを使って、3Dアセットやゲーム、動画、アニメーションをたくさん作っています。

でも気づいたら、作品がPCの中やXの投稿など色んな場所に散らばっていて、自分の作品をもっと良い形で見せる方法ってないのかなと思うようになりました。

AI時代のクリエイターには、ただ作品を並べるプロフィールじゃなくて、自分の作品や世界観を育てていける場所が必要なんじゃないかと思っています。

そこで、こんな実験を始めました。

自分だけのAI世界を持つこと。🌌

キャラクターが暮らす部屋
自分だけの創作スタジオ
自分の作品が集まる小さな宇宙
今まで作った漫画、画像、動画、���楽、コード作品、ゲームをそのまま置いて、自分らしい空間を作る。
さらに、他のAIクリエイターも遊びに来たり、作品を見たり、交流したり、一緒にRemixしたりできる場所。

MCPやSkillを使って、普段使っているCodexやClaude Codeともつなげながら、自分だけの世界を少しずつ育てていく。

これは最初のDemoです。

自分だけのAI世界を作ってみたい方、一緒に実験しませんか？

Back in college I took macro and micro econ and try so hard to understand the logic behind this.
The formulas never became images in my head P* = (a−c)/(b+d) meant nothing to me，but the gas lines of 1973 meant everything

So i decide to vibe coding a interactive game which will inspire others students like me to understand it .

A playable museum of economics where every formula is a brass machine you can operate and every principle comes with 24 seconds of historical footage

Built with @Tripo + @threejs + Seedance + Claude Fable

最近x有一个博主，vibe coding一个3d二次元风格的国际象棋，很有意思，我连夜搞一个��国象棋版本

不过我用的是类似王者荣耀的画风，对应不同的角色
另外我还花了几百块，用 @tripoai 做了3d模型GLB，在用 @threejs 来完善其他3d部分，然��联机用的是我们自己写的skill

大家如果有什么优化建议，可以跟我说，或者基于我开放的project, 自己也可以优化

在线试验可联机双人pk或者ai 对战 https://t.co/EIRY7a2Q8i

@sharkydev001 @thebuggeddev ai game will change the way of education

[Chrona @chronaworld]

@sharkydev001 What about you ?

[mr.bruce @chrona01]

Which direction would you bet on for AI-native game development?

AI coding + Three.js / Babylon.js / Bevy / other code-first engines

or

AI coding + Unity / Unreal / Godot through open MCP and agent interfaces

Personally, I’m betting on AI + Three.js, or other fully code-driven engines where agents can generate the assets, write the game logic, test everything, and deploy directly.

Traditional game engines still have a clear advantage today in visual fidelity, tooling, and asset completeness.

But over the long term, We believe the point of AI games isn’t simply to reproduce the kinds of games existing engines already make well.

It’s to create entirely new game experiences that were previously too difficult, expensive, or impossible to build—and turn the model into a camera for the imagination.

Which side are you on? #threejs #unity #godot #vibejam

Inspired by @levelsio's one-take game idea, i spent tons of time to create a one-take, multiplayer narrative game set in 1896 Gilded Age New York, drawn from the real business rivalries of America's tycoon era — railroads, steel, the press, and the monopoly investigations that followed.

It took me 20+ hours to finish just a small fragment of the story made by Seedance 2.0 ✖️ Codex ✖��� threejs

The twist vs a solo simulator: this isn't a walkthrough you watch. 2–4 players share one continuous story and vote together at every turning point, with a real stats layer underneath — capital, reputation, labor relations — so every choice carries consequences and one tycoon comes out on top.

Unlike previous models, Seedance 2.0 really gets the period right: elevated railways, gaslight, horse carts, a Bessemer converter — wardrobe and architecture all belong in 1896, with no modern objects sneaking in.

And because it takes reference images/video, I built 35 identity references (7 original composite characters × 5 angles). All 19 one-take story and vote-loop reels continue from the exact final frame of the previous one, with maps, leather and telegraph paper as physical wipe transitions — the characters' faces stay consistent across the whole storyline.

The one weak spot I see is text: newspapers and documents come out as distorted pseudo-English. So I designed around it — every paper surface in frame is deliberately blank or indistinct, and all text, voting and resource panels live in the HTML HUD layer instead. Film stays film; UI stays UI.

The look is purposely locked to a 35mm film grade — Seedance can do more photorealism than this, but a game needs every shot to share one consistent period feel. Combined with Three.js + single-file HTML (coded with Codex) and Sharky multiplayer skill (rooms, invite links, server-ordered sync), the whole thing runs as one seamless take.

📦 Everything is open source: the 75-minute five-act production bible, worldbuilding, character sheets, two Seedance prompt books, all video + GLB assets — plus a built-in "gilded-story-director" one-take continuation Skill and the Sharky multiplayer Skill. Feed the Skills to a Codex/Claude-style agent and it can write the next scene to spec: https://t.co/AWLrpnoRbo
