Slow Glass

A landing world for a fictional material — panes of "slow glass" that hold light and slowly compute their own image. Every visit renders a piece that never repeats.

The idea

Sell a material that doesn't exist — and make you believe it.

SDF raymarch · computed in your browser

"Slow glass" is a science-fiction conceit: glass so dense that light takes years to pass through it, so a pane becomes a slow recording of everything it once faced.

The brief I set myself was to build the product page for a material that can't be photographed — because the only honest way to show it is to generate it, live, in the browser. No stock imagery could do the job; the page itself had to be the artefact.

So the hero is a real WebGL shader. Each load seeds a different computation, so the "pane" you see is genuinely yours and won't recur. The copy leans into the fiction while the technology quietly proves it.

What went into it
Rendering

A live GLSL shader

The signature image is a fragment shader computed every frame, seeded per visit so no two panes match. The technique is the point, not a video of it.

Narrative

Scroll as slow reveal

Content unfolds on scroll to echo the material's own slowness — light, and meaning, arriving late. Motion is orchestrated, never scattered.

Restraint

Void, bone, one grey

A near-black ground and bone text let the computed light carry all the colour. The interface recedes so the artefact leads.

Performance

Bounded, and graceful

The shader is capped and paused when off-screen, with a static fallback for constrained devices — spectacle that still respects a battery.
