This interactive piece called Neural Network by Kim Seonghyun is pretty cool—it’s from Design Korea and shows how a neural network actually works, but in a visual, real-time way.

It reacts to people and generates visuals that mimic how the brain processes information, going through steps like analyzing, classifying, and predicting. The part shown here is the inference stage, where a trained model takes input and gives an output.

What’s interesting is how it was built—the creator () learned the basics of deep learning, trained a model using the MNIST dataset with PyTorch, then turned it into a visual experience using Processing. They also used OpenGL instancing so it can handle rendering a lot of elements smoothly.

It’s a really nice way of taking something that usually lives in code and making it something you can actually see and understand.

What do you think about it? 🤔💬

Check this out: some high school students from Wissahickon built a robot that can pick up balls and throw them into a bin while moving, and it does it really fast and accurately.

The robot uses smart design, sensors, and software to keep adjusting as it moves.

If teens can make things this advanced, the future of robotics is looking bright!

Chinese state media just released a fully AI-made animation about the US–Iran conflict, and it’s pretty much what you’d expect.

It uses a lot of symbols, has a strong message, and clearly shows its point of view. Calling it propaganda isn’t really a big stretch.

What’s more interesting is how people react to this kind of content.

On Western platforms, AI videos still get judged very quickly. Even if they look good, people often call them “AI slop” or argue about whether they should exist at all, instead of talking about the actual message.

On Chinese platforms like Bilibili, it feels very different. AI videos often get millions of views, show up in top posts, and people focus more on the idea and how well it’s made. Most of the time, no one even points out that it’s AI—it’s just another type of content.

This project uses OpenStreetMap data to recreate real-world environments inside Minecraft, generating roads, buildings, and terrain based on actual coordinates.

You can build your neighborhood, a full city, or any area block by block to match real life. It’s also fully open source, so you can run it locally, customize it, or build on top of it.

NVIDIA just revealed how they helped Disney bring Olaf to life, and it’s pretty wild 🤖❄️

They worked with Disney and DeepMind to show the tech behind the new Olaf animatronic, and it looks super advanced 👀

It runs on NVIDIA Isaac Sim, where engineers simulate real-world physics like gravity, balance, and movement with high accuracy ⚙️

Olaf also uses an NVIDIA Jetson computer, a small AI system that controls movement and interactions in real time 🧠

NVIDIA just dropped DLSS 5, the newest upgrade to their AI-powered game upscaling. 🎮✨

It’s using smarter neural rendering to crank out frames faster, boost performance, and make visuals look even closer to native quality.

If you love smooth gameplay without frying your GPU, this new version takes it to the next level. Thoughts? 🤔💬
