Write GLSL fragment shaders and watch them run as you type — WebGL2 with a WebGL1 fallback, compile errors on their lines, Shadertoy's iTime/iResolution/iMouse/iFrame, sliders and colour pickers for your own uniforms, pause, step and scrub, PNG and WebM export, .frag export for Shadertoy, glslViewer and other hosts, share links, and nine examples with lessons from UV gradients to raymarching and a Boing ball.
