Shader Playground
Experiments built around a shader or signal, not a named system
What it is
A looser category for pieces built directly around a shader, canvas technique, or an external signal like audio, rather than a specific named mathematical object. It's a sandbox for trying rendering ideas before they're developed enough to earn their own category - or for pieces that are interesting on their own terms without needing to be.
History & Contributors
Less a single mathematical lineage than a reflection of the demoscene and creative-coding traditions - communities like Shadertoy and GLSL Sandbox - that treat the fragment shader itself as an art medium. There's no equivalent of a Mandelbrot or a Möbius here to credit; the point of this category is exploration rather than reproducing a named classical result.
Latest Trends
Audio-reactive visuals (mapping a live signal's frequency/amplitude straight into shader uniforms) and general-purpose "blank canvas" shader components that get repurposed for whatever the next experiment needs, rather than being rebuilt from scratch each time.
