Background

WebGL Fluid Simulation is a widely shared interactive demo showcasing real-time fluid dynamics rendered directly in the browser using WebGL, originally built by developer Pavel Dobryakov as a technical showcase rather than a traditional game. It became popular far beyond programming circles for how genuinely mesmerizing and satisfying it is to simply move your cursor and watch photorealistic, colorful fluid swirl and react in real time.

As a piece of generative, interactive art built on real physics simulation rather than pre-rendered animation, it represents a category of "toy" experiences that blur the line between technical demonstration and genuinely engaging interactive entertainment.

How to Play

• Mouse — move your cursor across the screen to stir and swirl the fluid simulation.
• Click to add bursts of color and force into the simulation.
• Experiment with different movement patterns for varied visual effects.
• Enjoy the real-time, physics-driven visual display purely for its own sake.

Goal & Purpose

There's no objective — this is a purely interactive visual toy, meant to be enjoyed for the mesmerizing, ever-changing patterns your mouse movements create in the simulated fluid.

Why Play WebGL Fluid Simulation

It's a genuinely mesmerizing, satisfying interactive experience unlike a traditional game. GBK Games also has Townscaper for another purely creative, objective-free browser toy.
