Aurora Shader Background
A full-screen fragment shader folds three ribbons of aurora colour through layered fbm noise above a dark horizon, lets the pointer bend the curtains with a lagged lens, adds grain and a vignette; a CSS gradient stands in without WebGL or with reduced motion.

medium Noise Gradient Mesh Background
A full-screen fragment shader blends four drifting colour fields through domain-warped simplex noise, adds animated film grain and a soft vignette, and lets the pointer gently pull the warp; a CSS gradient stands in when WebGL or motion is unavailable.

medium Incense Ribbon
One incense stick in a glazed bowl of ash on ivory paper. A thin smoke ribbon rises straight from the ember, curls into turbulence and fades; move the pointer near it and your breath bends it. Six blends.

medium Velvet Nap
Full-screen crushed velvet shaded fibre by fibre. Drag across it and the pile flips along your stroke, leaving lighter or darker trails that slowly lie back down. Eight colourways, light-first.

medium Fractal Topography Contours
A full-bleed topographic map drawn in one fragment shader: a slowly drifting fractal terrain traced as pixel-perfect contour lines with thicker index contours, an optional elevation tint, and a soft hill that rises under the pointer in the accent colour.
