Triprism

Triprism treats the interface as part of the instrument. The glass, wall light, cast shadow, caustic and spectrum are rendered as a retained WebGPU graph rather than a looping video or decorative image. Moving across the face changes the virtual lamp aim and camera orbit, so the incoming beam and its split spectrum respond as one physical scene; when the pointer rests, the scene returns to a slow automatic orbit.

The audio path stays deliberately small. A bounded feedback delay runs into the shared algorithmic reverb, then a compressor glues the tail before the final level stage. The seven public controls are the whole signal path; the face does not hide a second browser-only effect behind the animation.

WebGPU is the visual enhancement, not an audio requirement. If the browser cannot start the renderer, the effect and its controls remain usable and the face explains that it has switched to audio-only mode.
