The same sunlit concrete box, ported to WebGPU, with a striped plus tumbling through the sun shaft. The path tracer runs as a compute shader and keeps a short memory while the plus moves the light around; an edge-aware à-trous filter cleans what that leaves noisy, so orbiting stays smooth. Each light probe gets a workgroup of 64 lanes that trace its rays side by side. Panel (H) shows each pass's GPU time.

A concrete box in the sky: sun shafts through one window, lit a second time by its own bounce light — one blue-noise ray a pixel, averaged frame over frame until the grain settles, while a chrome torus mirrors the room. Orbit in and out through the walls, and click an object to move or turn it.

A sculpted hand in grainy black and white, fingers rolling in a seamless loop. Bring the cursor into its grasp and the hand catches it.

A quietly waiting sheet ghost — simulated cloth, wandering idle motion, and a gaze that notices you in the dark.

Concrete column field, refracting glass cubes, and whirling colored light trails over base fog.

Tropical light filtering through large fronds.

Rotating physical blocks in a neat field layout.

Soft blocks of colour, crisp in one place and smeared in the next, ghosted like a video starved of bitrate and seen through a CRT's slot mask. Click for a new frame, R to roll the dice on every setting, S to save it at 4K.

An endless vertical list of names — fast, smooth scrolling and paired background and preview colors that crossfade on hover.

Raymarched aurora curtains after kishimisu — spectral ribbons that drift and fold in deep space, pulsing to a generated beat.

Living gradients that cross-fade curated palettes, blended in OKLab for natural color.

Five orbiting petal blobs with palette flow and soft fog wash.

Noise-warped diagonal stripes with live-tweakable colors and warp.

Procedural sky gradients and atmospheric depth.

A slow monochrome ink wash shaped by layered noise.

Shader tunnel with a deep-space motion feel.

Capsules and beads pile up against a pane — depth is spent as blur, so the far ones smear into the fog.

A pane of segmented log-compression flutes over the left half of a soft drifting wash. The cursor sits behind the glass.

A vertical glass line warping thin black wavy lines on white.

Refracted line-field glass lighting. The lines bend away from the pointer and spring back.

A 5×3 grid of point lenses refracting a flowing cosine wash background. They shy away from the pointer and spring back.

Straight vertical glass lines refracting a gold cosine palette. The strips under the pointer grow wider.

A fixed strip of bent glass near the top refracts the article text with chromatic aberration as you scroll.

Staple images to a telephone pole — drop one anywhere and it sticks where it lands, a few degrees off true.

Shape a low-poly island with seeded noise, elevation bands, and live terrain controls.

Read the wind, pull back, and spring a tiny frog across a branching lily-pad course.
