An abstract clock rendered in real-time by a WebGL fragment shader, patterns shift with each second.

About this tool

Shader Clock is a free online visual effect. Abstract art Shader clock pattern changing over time. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.

After opening the page, a full-screen clock will be displayed, and the time numbers will be rendered in real time with a shader program, producing various cool visual effects: liquid flow, pixelization, light refraction, etc. You can switch between different shader styles.

The whole process is pure front-end animation. WebGL's GLSL shader program uses mathematical tools such as polar coordinates and noise functions to calculate the color of each pixel in real time. Smooth performance and amazing results.

Ideal for use as a desktop clock, web decoration, or simply appreciating the art of shader programming. The implementation principle is a combination of SDF (directed distance field) and mathematical functions.

Shader Clock is a clock special effect based on WebGL shaders. It uses mathematical formulas to render the time display in real time, and the effect is cool.
