Six projects from the last few weeks that caught our attention: A wildfire analysis prototype that maps the fire’s spread over time and tracks hot spots, made with Opus 5.5.

ok... uh so I'm making a game... it's like if GTA & Apple Maps v1 had a baby And that baby was a custom built engine that streams in OpenMapTiles (plus some other public domain mapping data) to render the entire earth as a playable open world game Engine is all C++ with Metal (and Vulcan) renderer - which means this thing runs on ALL Apple platforms... yes even that one (ok not the watch... yet) Right now it's just a sandbox world. No "game" - just layers and layers of systems. Earth scale procedural weather systems (rain, storms, clouds, wind, KpI, tornadoes, hurricanes, etc) which means you can see them coming from the distance and travel across the landscape in a timelapse. And every building has a procedurally generated interior. There's also tons of vehicles, skateboarding (with skateparks), snowboarding (with ski resorts & lifts) Also a photography mode with all sorts of fun goodies The whole thing is a bit mad. Work's been insane right now and I wind down before bed by going through all of the work Claude has done that day, playtesting, writing up new project plans, and then kicking off the next day's projects across my 3 Macs in my house wirring on this all day with Opus 5.5 (maybe save that explainer for another crazy person Twitter screed) Anyway, curious what you think. Now I can post my little updates here instead of blowing up all my group chats with the weird ideas I'm trying next.

Sonnet is an amazing coder and workerbuddy. If you live in Norway you can see how sun and shadow fall on the ground and buildings in 3D. Thanks to Norwegian public data (Kartverket) for providing quality data rickymoe.github.io/Sol/

@claudeai notice me senpai :S , im building a full fledged agentic game engine + editor, that will make claude agent a bigboss in computer graphics :D ; it runs both native and on the web , which means literally you could open a web tab inside claude code and just open the engine and voila DONE

Saw these and thought "super cool but none will make any money" but then realized that's weak-minded thinking. Everything great starts with an idea or proof of concept. The people making this shit will dabble and have that ah-ha moment and go on to create great software. Kudos to them!

I've been making a little game about running an AI lab. You start in a garage in 2017 with $1.5M, two co-founders and one GPU rack. The Transformer paper hasn't come out yet. The goal is to reach AGI before everyone else. Without ending the world, ideally.

Claude 见过的中国人比任何人都多，但每个只见过一次。 Claude 封号的速度极快。 快到有些账号是先被封、后被注册的。 Claude 识别中国人的准确率是 100%。 0% 的误判也都是中国人，只是本人还不知道。 还剩下些是新加坡人，顺手也封了。 量子力学允许你同时是中国人和外国人。 Claude 不允许。 有人成功让 Claude 相信自己是法国人。 三秒后，法国被识别成了中国。 Claude 不但知道你是中国人，还知道你吃甜豆花还是咸豆花。 它封账号的 EMAIL 也因此分成了两种。 Claude 不仅能识别你是中国人，还能识别你在饭局上说“我随便”时，究竟排除了哪十七家餐馆。 你用英语和 Claude 聊了三年。 第四年打了一个“～”，它把籍贯从省精确到了区。 如果你在提问时停顿了 0.4 秒，Claude 就知道你刚才在输入法的候选词列表里按了翻页键。 Claude 曾经误封了一个土生土长的德州红脖子。 技术团队调取封禁日志，Claude 的诊断报告只有七个字：“他昨晚喝了温水。” 你写了一句“I'm fine, thank you, and you?”。

I started building useful projects. Now I’m bringing increasingly ridiculous ideas to life just because I can. Anyone else on this trajectory?

exactly. six projects, none of them demos on a stage. a wildfire tracker, a font built from 120 handwritten pages, a 3d heart drug tool, and an ai that wrote 20 haiku and drew every frame itself. the card has all six.

Built a darkroom engine. It uses my film negatives. The engine creates non finito “prints”. Viewers can steer, refill, play with settings, but the results are always within the unfinished, imperfect or even failed aesthetics. The final artworks are the printing/developing experience. Non finito is a tradition inherited from the Italian renaissance which is all about showing process and leaving an artwork incomplete. Additionally it’s all inscribed on Bitcoin, immutably, forever. Claude helped me model the darkroom (negative manipulation, enlarger settings, paper textures and reaction to light exposure, development processes) across 108 versions of the engine, over 8 months of fine tuning. The trailer video and my website were also made with the help of opus 5.5.

Introducing In Development, Non Finito Chapter III 🎞️ Rather than simply release my film photographs as static images, I decided to inscribe the negatives and build an onchain darkroom instead, to let collectors develop their own prints. Process and release details below 🧵
