Grok Bot is already here and it’s different While regular Grok chats and answers questions, this new agent from xAI gets its own virtual machine, plugs into your tools, and actually finishes the work. A developer built a full sci-fi platformer with Grok 4.6 and Three.js, then handed it straight to Grok Bot for gameplay feedback. No more just talking about ideas. Start shipping them.

GROK 3 JUST BUILT A FULL 3D MULTIPLAYER GAME—NO SWEAT AI-powered game development just took a massive leap. A full 3D single & multiplayer game—complete with raycasting, AI-driven enemies, and procedural city generation—was built using Grok 3. No struggling with token limits, no hitting walls with confused models. Just a working game. Grok 3 handled everything: speed boosters, AI bot patrols, collision detection, health systems, and even an algorithm to auto-generate cities. Multiplayer? Grok synced player movement, shots, and even built a login system with character selection. Running on an Express server with WebSockets, this game proves one thing—Grok 3 is amazing. Source: Dan

This is my new opensource project with WEBGL2 & Three.js , my goal was to build a third person template of a samurai, so I built 3 techniques ( using the katana ) & 3 magic abilities which are fully procedural. katana fire made of a real raymarched volume, ragdoll with no physics engine, Skeleton was done in mixamo so that it's easy to swap character & a character editor. A lot of manual work done & I used Opus 5 Anthropic help to speed up my vision. Live link: Source code:

In June 1937 at Neuhardenberg, pilot Erich Warsitz (posibly the first jet pilot) ignited the von Braun Liquid Fuel Rocket Engine on his Heinkel He 112 after climbing to altitude and shutting down the Jumo piston engine. Smoke and fire quickly filled the cockpit due to exhaust flowing back into the fuselage. Despite the wheels-up landing and having the fuselage on fire, it proved to official circles that an aircraft could be flown satisfactorily with a back-thrust system through the rear without causing an aircraft to flip or become uncontrollable. It convinced the German Air Ministry (RLM) that rocket-powered flight was feasible, leading directly to the development of the purpose-built Heinkel He 176.

Tucker Carlson horrified as geoengineering expert Dane Wigington identifies what’s really being sprayed in the skies. Hint: it’s not just condensation. Dane Wigington named seven troubling substances: 1.) Aluminum 2.) Barium 3.) Strontium 4.) Manganese 5.) Surfactants 6.) Polymer fibers 7.) Graphene Tucker asked who the heck is doing this, and Wigington replied: “All roads lead to those who print the money,” naming DoD and DARPA as “coordinating entities.” Responding to the condensation trail narrative, which Wigington called “one of the greatest lies ever perpetrated on populations all over the world,” he pointed out an inconvenient fact that refutes that claim: “All military tankers and all commercial aircraft are equipped with what’s known as a high-bypass turbofan jet engine. That’s a jet-powered fan. Ninety percent of the air that moves through that engine is not combusted. So by design, that engine is NEARLY INCAPABLE of producing any condensation material except under rare and extreme circumstances.”

Vibe coded a fun little "Breakout-inspired" game where you control a gnome with a cannon trying to defend its garden against an onslaught of insects. Cursor was used to make this game, I mainly alternated between Grok Code Fast, GPT 5 and Sonnet 4.5 models. I used LOVE2D game framework/engine, it's really growing on me. The art for this game are hand drawn by me. Music and sound effects from itch.

GLM-5.1 > Claude Code (Opus 4.6)? I'm tripping or CC has become very bad but built a Three.js racing game to eval and it's extremely impressive. Thoughts: - One-shot car physics with real drift mechanics (this is hard) - My fav part: Awesome at self iterating (with no vision!) created 20+ Bun.WebView debugging tools to drive the car programmatically and read game state. Proved a winding bug with vector math without ever seeing the screen - 531-line racing AI in a single write: 4 personalities, curvature map, racing lines, tactical drifting. Built telemetry tools to compare player vs AI speed curves and data-tuned parameters - All assets from scratch: 3D models, procedural textures, sky shader, engine sounds, spatial AI audio! - Can do hard math: proved road normals pointed DOWN via vector cross products, computed track curvature normalized by arc length to tune AI cornering speed You are going to hear about this model a lot in the next months - open source let's go 🚀🚀

The Tri-Engined jet with four engines. The HS Trident was, obviously, a tri-jet, using three Rolls-Royce Spey engines. However, the final version of it, the 1969 Trident 3 - seen here in this video - was stretched for extra seating and range. And so what did HS do? They installed a fourth engine, a "booster" in the tail, a RR RB.162 originally intended as a lift engine for VTOL applications (the ill-fated Mirage IV was one of the few jets that used such an engine) With three or four engines, for various reasons - including the ever-present political mongerings in UK aviation, only axed with Airbus - the Trident was not a success, and only 117 were built. (Also, wouldn´t it be simple to change to different, more powerful engines? Unfortunately, it wasn´t possible on the Trident... so no wonder other customers opted for the more flexible 727 and DC-9)

The E90 330i represents a type of everyday BMW that no longer exists. The N52 straight-six delivers its power in a clean, rising curve, with no waiting and no surge. Compared with the later F30 328i and its N20 turbo, the older car feels lighter on its feet because the throttle is connected directly to displacement. As an ownership proposition it is simple: no high-pressure fuel systems, no heat-soaked turbo plumbing, just an engine that likes revs and regular maintenance. The numbers may be similar to the turbo successor, but the sound is the reason, plus the reliability is better.

Fable 5 built this real-time ocean scene directly in the browser using Three.js, WebGPU and TSL, with no engine and no baked assets. The interesting part is not just that the water looks good. The whole system is being simulated: wave spectrum, GPU FFT, foam generation and refracted-ray caustics, all running live. This is exactly where frontier models start becoming genuinely useful for technical graphics work. Not by replacing years of rendering research, but by compressing the path from complex math to a working interactive result. A small, focused scene, but technically very serious. Cc: Adem Vessell

BMW M3, E92. 414 hp. From a 4.0L naturally aspirated V8. Revving to 8,400 rpm with no turbo. 0–100 km/h in around 4.6 seconds. Back then, 400 hp meant revs and sound in the 2000s. Not torque, not instant speed. This was about the experience, this car wanted you to rev the engine hard, this is a backroads car for going fast. One of the last naturally aspirated M3s. Compared to a modern M340i with maybe similar power, this feels slower, but this M3 is way better feeling and its a V8 M3, the only V8 M3 and the older M3's feel way way more alive.

Holy Opus 5 🤯 i think you people never saw this level of creativity and Three.js use ever music , sound , blackhole everything is procedurally generated no external assets Prompt : Please develop a single, self-contained HTML file featuring an extraordinary 3D audio visualizer. The visualizer should be driven by a full-length, highly catchy EDM/dubstep track titled 'SINGULARITY', seamlessly integrating the audio playback with dynamic, high-performance 3D visual effects.

Today, this video shared as Angara Airlines An-24 crash Near Tynda, Russia. Claiming All 48 Lives On Board But the real story of this video is below: An Ilyushin Il-112V military transport aircraft prototype crashed in a forested area near Kubinka Air Base, Russia, killing all three people on board. The aircraft took off from Zhukovsky International Airport near Moscow at 10:35 local time, landed at Kubinka Air Base at 11:09, and then departed for a test flight at 11:14. Four minutes into the test flight, the crew reported a fire in the no.2 (right) engine. Video evidence of the flight’s final moments shows the aircraft with a severe fire in the no.2 engine, gradually rolling to the right while losing altitude. The nose then pitched down, and the aircraft rolled inverted at low altitude before crashing into trees and erupting in flames.

🚨 JAY LENO JUST PULLED UP IN A CAR THAT RUNS ON PERFUME OR TEQUILA — AND IT SOUNDS LIKE A GIANT VACUUM Jay Leno just rolled up in one of the strangest cars ever built: the 1963 Chrysler Turbine Car, with bodies hand-built by Ghia in Italy. Instead of a normal piston engine, it uses a jet-style turbine. And when it starts up, it doesn’t rumble like a V8. It sounds like a giant vacuum cleaner spooling up. Then Leno shows the part that catches everyone off guard first. He puts a bottle of water on the engine while it’s running… and it barely ripples. Almost no vibration at all while the turbine spins. Then he explains why this car is so bizarre. The engine is designed to run on almost anything that burns: • Diesel • Kerosene • Jet fuel • Heating oil • Cooking oil Leno says when Chrysler took the car to Mexico, they ran it on tequila. When they brought it to France, they filled the tank with Chanel No.5 perfume. Only 9 of these Chrysler Turbine Cars are believed to still exist today. If your car could run on almost anything that burns... what would you try putting in the tank first?

Two British men built the machine that changed the world. 🇬🇧⚙️ An ironmonger. And a plumber. You've never heard of either of them. 1690s. Britain's mines were drowning. The deeper they went, the more they flooded. Men drowned in those tunnels. Children hauled water out by hand. Bucket by bucket. When the water won, the mine closed. And the village starved. Thomas Newcomen. Ironmonger. Dartmouth, Devon. John Calley. Plumber and glazier. Both Baptists. Both barred from the universities. Both outsiders. One knew metal. The other knew water. They worked for a decade. With their own money. No patron. No institution. Just a forge, a bench, and an idea. For years, it wouldn't work. Then cold water leaked through a crack. The steam condensed instantly. The engine fired. The flaw was the answer. 1712. A coal mine near Dudley Castle. They built their engine at the pit head. Twelve strokes a minute. Ten gallons a stroke. Not horses. Not children. A machine. But they couldn't patent it. Thomas Savery already held the rights — to every engine that raised water by fire. Even machines he never built. Calley died in Holland. 1725. Far from home. Still working on their engine. Newcomen died in London. 1729. His grave is lost. Decades later, a young man was asked to fix a model of their engine. While fixing it, he saw how to improve it. His name was James Watt. You've heard of him. But without them, there is no engine for Watt to fix. No Industrial Revolution. No modern world. Every factory. Every railway. Every power station. British men. An ironmonger. And a plumber. And that's only a fraction of what we have done for the world. 🇬🇧 Names like theirs are buried everywhere. We dig them out. No sponsors. No algorithms. Just a community that believes its true history matters. Our community makes that happen 👉 Be part of us.🙏 Be Proud Of Us. 🇬🇧

In this experiment I wanted to try something with facial expressions and have it work with native Unreal Engine tools. I did find that generating the head with an open mouth helped to get some extra details. Creating those blend shapes was still not easy and this result is far from perfect. Ideally i want 58 generated expression references and have AI figure that out haha. btw first time baking the high poly details onto the low poly generated character. That worked surprisingly well! Endresult has 34k triangles! Built this character in 4 separate parts in Blender and generated each part in Hunyuan 3D Studio. The original references came from Nano Banana 2 and Grok. Trellis 2 in ComfyUI for the texturing. The animation was done with Control Rig in UEFN / Unreal Engine. With all the experiments so far, file and version management start to become a challenge. Getting files from different platforms with each platform having their own filename logic. I’ll have to find something to keep it more organized. Any suggestions?

Inside Pratt & Whitney PT6A-67B engine, two turbine systems spin in opposite directions at tens of thousands of rpm, yet they aren't mechanically connected at all. The gas generator spool reaches roughly 37,500 rpm. Its hot gas drives an independent power turbine at nearly 30,000 rpm, producing up to 1,200 shp. Then there is the gearbox. A compact two stage reduction system has to take that 30,000 rpm input and drop it all the way down to just 1,700 rpm at the propeller, while transmitting roughly 5,000 Nm of torque reliably, flight after flight under all kinds of loads and conditions. All of this happens inside an engines that weighs only about 235 kgs, with interstage turbine temperatures reaching roughly 800°C during takeoff. That combination of extreme speeds, temperatures and mechanical simplicity helped make the PT6 one of the most successful turboprop engines ever built. More than 64,000+ engines have been built and they have accumulated more than 500 million flight hours so far. Whether it is a jet engine or almost any other machine, the really successful designs tend to have one thing in common, the materials, mechanics and overall design work together so well that something incredibly complex ends up looking almost simple.
