dsh-particle-whale

The default DSH Desktop background is a still, blank canvas. While waiting for the AI to think or stream, the only thing moving on screen is the text. dsh-particle-whale drops a living, particle-built whale into that space using native Three.js and WebGL shaders — not a texture, not a 2D loop, but a volumetric creature with real locomotion and reactive state.

Three pillars carry the experience. The volumetric particle mesh uses distance-transform mapping to inflate a 2D silhouette into a full 3D spindle body with surface normals, specular highlights, and Fresnel rim glow. Head-first swimming means the head sets the heading, traveling waves propagate down the spine to the flukes, and the whale banks smoothly into turns. Reactive agent state: idle brings a calm, full-screen cruise; thinking or streaming sends it gliding to the top-right as a compact companion with bioluminescent pulse waves; a new session triggers a clean nebula scatter-and-reassemble while casual clicks are silently ignored.

An 88%-translucent frosted-glass input card, dark/light adaptive particle palettes, and instanced-mesh rendering holding 60–120 FPS round out the package — all without blocking interaction. It is built for anyone who lives in DSH Desktop for code, chat, or agent runs: the whale never steals your focus, but those few seconds you wait for a reply, something is finally swimming with you.
