It’s incredible that you can let Opus 5 run for two hours in Claude Code and get a cinematic Three.js movie inside one HTML file. It created the story, scenes, transitions, camera moves, and procedural world. Higgsfield generated the narration, sound effects, and music. I mostly helped with references for more realistic grass, added the skills I use, and asked it to keep verifying its work. It’s all open source, so you can play with the code.

Using his prompt, I asked Claude Opus 5 to recreate Fallout in a single HTML file. It gave me a fully explorable world with unique landmarks, a functional Pip-Boy, characters with dialogue trees, and it’s now working on adding a vault! And the entire file is only 2.3 MB.

This looks like it came straight out of a Studio Ghibli film 😭🔥 Wind-blown hair. Swaying grass. A billowing shirt. All made in Blender by @BirdChen3D — as a tribute to Miyazaki's final film, The Boy and the Heron. #Blender3D #B3D #StudioGhibli #AnimeArt #NPR #3DAnimation

This morning, History was made in South Dakota. A Single Supercell produced a wind gust of 131mph, wind normally seen in EF2 Tornadoes or Category 4 Hurricanes. This is the second Highest Wind Gust from a Thunderstorm ever recorded in the United States. This was that Storm

I was skeptical about giving GLM-5.2 the task to build a super mario snes style game in a single HTML file so i ran the test on Opus and also on GLM-5.2 Opus didnt even try to make a game or made something but it wasn't a game GLM-5.2 one shotted a pretty functional game.. WILD

It cost me $15 on the Epic Games Store and a few million AI tokens to build this web-native grass simulation. Demo in the comments. Epic Games owns Quixel, a collection of high-quality Megascans. You can use them in Three.js, which is exactly what we did in this demo. The butterflies, flowers, and surfaces all come from Megascans. The long grass and wind simulation were converted from Blender Geometry Nodes simulations, which is why it feels so good. Then add an HDRI, set up the lighting, and boom—you have highly realistic grass rendered fully on the web. While it’s something built with AI, a non-designer without a certain set of skills would never be able to do this. You still need the knowledge, terminology, and understanding required to glue all these technologies together.

How I made The Fluffiest Grass on the Web!🍀 >1 BILLION Blades of Grass!🤯 I spent 200 hours researching how to make fluffy grass for the web! I wanted to use a technique that was simple, but extremely effective and performant. Here's how I did it: PART 1 - CPU Optimization (🧵0/10) #threejs #webgl #gamedev #3D

I made a Claude Code skill that generates conference posters 🛠️ Instead of a static PDF, it outputs a single HTML file — drag to resize columns, swap sections, adjust fonts, then give your layout back to Claude. 🔁 🔗 Skill 👉

One of our focuses of this next upcoming patch has been to make improvements to our wind effects. All in-game foliage now has more realistic movement - in grassland areas, wind-blown grass will now flutter in the wind, and during stormy weather foliage will respond dynamically to stronger winds by swaying left and right. Coming to you very soon in the next full game patch! #pathoftitans #dinosaurs

Claude Opus 5 just made the best Remotion video I have ever seen. Perfect transitions. Music timing locked to the frame. Branding nailed without me asking. Fable 5 held this crown for months. Opus 5 took it in one prompt. Opus 5 significantly outperforms Fable 5 at marketing videos, and it is not close. Watch this and remember Opus 5 made it.

There's a British mansion in the background. This mansion used to overlook paradise. Now it overlooks third world invaders who are probably illegally parking on the field and also illegally barbecuing on the grass. So unbelievably depressing.

I ran Opus 5 for two hours to recreate Sakura Crossing as an explorable Three.js version of San Francisco. I had Codex use the Claude Code CLI, so the two agents worked on the same build. The whole site is packaged as a single HTML file. Three.js site: Original repo:

CNN: He claimed that China builds a lot of wind turbines and manufactures them for others, but refuses to use it itself, barely uses wind power. In fact, China is the world leader in the use of wind power. It is building additional wind power in China far faster than the pace at which the U.S. Is building in the United States itself. So the idea that China is just, you know, foisting this terrible source of energy on other countries while refusing to use it is a reversal of reality.

Martian wind. A series of 126 x/y tilting mechanical devices connected to tall dried grass stalks by artist David Bowen. The mechanisms will tilt, move and sway based on data collected from the wind sensor on the Perseverance Mars rover. [📹 davidbowenart]

Read the file for the “The DiVine” saying that they're supposed to get angry when you walk on the grass, so I made some Custom/Fan SFX for them #pressure #pressure_roblox
