GLSL demos you can play with right now

Hundreds of GLSL demos, each running live on its creator's own site: some of them vibe-coded with AI, all of them playable in your browser with nothing to install. Press a card to play one on its own page, or start the cruise to ride through them one after another.

GLSL is the little language that runs on your graphics card, once per pixel, every frame. That is how a few dozen lines turn into fractals, plasma, raymarched worlds and liquid light, and this stop is full of them.

Questions about glsl

What is GLSL?

The OpenGL Shading Language: a C-like language for shaders, the programs a GPU runs in parallel. In the browser it is what WebGL executes.

Why are shader demos so smooth?

Because the GPU computes every pixel at once instead of one after another. That parallelism is what makes effects possible here that would crawl on the CPU.

Is it normal for my fan to spin up?

Yes. A full-screen shader keeps the graphics card busy every frame. Press next when you have seen enough and the fan will settle down.
