01 — Genesis

First, a held breath.

The sphere is never drawn. It is found — by rays that walk into the dark and ask, at every step, how far is the nearest surface? The answer is a single number. The number is the world.

FieldSigned distance StateCoherent Temp2.4 kK

02 — Turbulence

Then the field forgets its shape.

A gyroid moves through the sphere the way weather moves through a coastline. sin x · cos y, folded three ways — interference becomes structure, structure becomes storm.

FieldGyroid lattice StateAgitated Temp5.8 kK

03 — Bloom

Light behaves like oil on water.

Every colour on this page is one cosine, phase-shifted. Thin-film iridescence, faked with four numbers — the surface blooms because the palette turns with your point of view.

Fieldfbm displacement StateRadiant Temp7.1 kK

04 — Stillness

The storm settles into glass.

What remains is the memory of turbulence: a surface that has stopped moving but not stopped listening. Press it, and the field remembers everything.
