You’re looking at water.
Except it isn’t water.
It swirls, ripples, and crashes just like the real thing. But it’s code.
Matsuoka built a fluid simulation that runs in a browser using WebGPU. It’s fast. It’s beautiful. It makes you forget that pixels aren’t molecules.
But here’s the trick.
The magic isn’t in the water. It’s in the grid.
A bad simulation tries to track every single drop. It gets stuck calculating who’s next to who, burning up speed and struggling to scale.
A smart simulation lets the grid do the work. Instead of making particles talk to each other, it makes them talk to the space between them.
It turns chaos into a conversation.
That’s why it works. That’s why it runs in real time.
And that’s how everything great is built.
The best teams aren’t just collections of brilliant people. They are structured in a way that allows brilliance to flow.
The best systems don’t track every moving part. They define the space that keeps everything moving.
The grid is invisible. Until you see it. And then you see it everywhere.
