dsh-whale-bg

The DeepSeek Harness Web UI is maturing on the functional side, but the visuals can still feel plain. dsh-whale-bg breaks the iconic whale silhouette into a swarm of varied-size particle tiles that glide, assemble, and glow quietly in the background, never stealing focus from your conversation yet adding a layer of ceremony to every session.

The interactions are where things get interesting. On first load, particles drift from a scattered state and assemble into the whale; while idle, the tail rides a travelling wave; a nearby cursor pushes tiles radially with subtle per-tile angle noise, like a gentle airflow; and the flashlight lighting keeps the whale nearly invisible until the mouse comes within a small radius, where it brightens into view. The light theme uses deep-blue multiply blending, the dark theme uses screen blending for a soft glow, and the whole decorative layer is capped at 30 FPS to stay cheap to render.

If you run the dsh Web profile and want a touch of liveliness without a performance hit, this MIT-licensed community plugin is worth a look. Every tunable, from particle density to flashlight radius, lives in a single file (src/client.ts), so you can dial the look to taste.
