DeepSeek Harness weather plugin adds 25 wallpapers and rendering upgrades

On 2026-11-11 at 10:06, a post appeared on V2EX announcing the open-sourcing of “檐下” (Shelter), a weather-themed plugin for DSH (DeepSeek Harness, DeepSeek's desktop / Web workbench). The plugin is released under the MIT license, with code available at https://github.com/ifer47/dsh-theme-shelter. It offers three dynamic scenes — rain, snow, and hearth fire — together with realistic audio and day-night switching.

According to the post, the plugin normally shows only a single 28 px button in the bottom-right corner. Opening that panel reveals controls for scene, intensity, color scheme, lightning, sound, and night mode; when the panel is closed, the weather keeps running quietly in the background. The rain effect is not random lines: each raindrop's terminal velocity is computed from its diameter as v = 9.2·√(d/3), the on-screen speed is then multiplied by 1/z for perspective, and trail length equals speed × 6 ms exposure, clamped to 7–70 px, so drizzle leaves short trails while heavy rain leaves long ones. Raindrop slant is taken as atan(wind / velocity), making fine rain斜 relative to暴雨, and each landing splash consists of 5–9 ellipsoids launched at 16% of the landing speed, oscillating and deforming along their own direction in flight. The snow effect uses a coherent wind field rather than moving each flake independently; the hearth scene includes a warm glow at the base, rising sparks, and slowly ascending smoke. The post also mentions that two crystal forms travel through the same wind field and that accumulated snow at the bottom grows as more falls, plus the detail that drops below 0.5 mm stay spherical because surface tension dominates. At this point only this single developer-written post is available, with no third-party verification or follow-up coverage.
