Audiovisual Programming Workshop by Charlie Roberts. Part 1.
summary
Live shader coding shows how tiny GLSL fragment programs (often ~13–14 lines) run once per pixel on the GPU, using uniforms like time and a UV position to make oscillators and striped patterns. The demo uses the web tool the force (per-keystroke recompilation you can freeze by injecting errors), references higher-level layers Hydra and marching Jas, and demonstrates how audio meters or CPU-updated uniforms sync sound to visuals in realtime.
