1karm

1karm is an original horror homage to the visual vocabulary of the Thousand-Hand Guan Yin dance, performed by the China Disabled People's Performing Art Troupe (choreography by Zhang Jigang). Every pose is authored here. A zombie girl dances in a loop in a dark, rainy forest. The "thousand hands" come from echo layers of her own arms, so the scene reads as one body with many arms.

The scene

• Presets: haunted forest, a void stage and a fog-bound graveyard, all loaded as data rather than code.
• Weather director: wind, rain with splashes and ripples, ground mist, and seeded Poisson lightning that lights the scene through the post pipeline.
• Post FX: bloom, grain, vignette and chromatic aberration, plus a half-resolution depth pre-pass so fog sheets fade softly against geometry.
• Possession: a tunable undead layer that drives how wrong the dancer looks, from human to fully possessed.

The hidden admin

Visitors only ever see the scene. Behind a hotkey sits a Svelte 5 glass panel, loaded as a lazy chunk, whose controls are generated from the scene's own module registry. It swaps presets and dancers, tunes the weather live and changes quality tiers. An editor mode adds a transform gizmo, snapping and a capture camera. Settings autosave, and presets export and import with version-keyed migrations.

Built to be checked

Quality tiers cap the pixel ratio, shadows and particle counts so phones stay smooth. Playwright scripts drive the real admin panel, the editor, weather, hero swaps and possession, and check for leaks across repeated preset swaps. A Vitest suite covers the rig maps and pose maths. All models and textures are CC0 (Quaternius, Kenney, Poly Haven) and listed in generated credits.
