Luminous bands of light refract through invisible fabric — a persistent, living backdrop that breathes beneath your content.
The effect stays fixed behind all content. Scroll freely — the silk keeps flowing, uninterrupted.
A single fragment shader with layered simplex noise creates the cloth-like bands. No textures, no video — just math on the GPU.
Noise derivatives simulate light glancing off the fabric surface, giving each fold its glossy sheen.
