Generative pieces.

Two kinds: standalone pages with their own controls, and site backgrounds that take over this page in place. The eye toggle in the bottom right brings the chrome back when you're done.

Three.js · simplex-noise · lil-gui

2026

Procedurally generated Tucson desert, built as a zen garden out of love for Tucson and the desert. In memory of my brother Larry William Pierson (1966-2025) and my Aunt Alice Gutierrez, born Alice Pierson (1949-2026). Layered terrain, scattered rocks, plants, and sky.

WebGL2 compute · ASCII arrows

2026

Reynolds boids — separation, alignment, cohesion. The cursor scatters the flock. Rendered as a field of ASCII arrows oriented to each boid's heading.

WebGL2 · ASCII density ramp

2026

Navier–Stokes on the GPU with vorticity confinement. Ambient emitters keep things moving; click to splat new density into the field.

CPU · Stefan Gustavson

2025

A seeded 2D simplex field, sampled to characters and quietly drifting in time. The classic procedural primitive, made visible.

CPU · 2D ray tracing

2025

Light rays refracting through floating glass prisms — dispersion by wavelength splits white light into a spectrum.

CPU · 3D rasterization

2025

Tori, cones, and cubes rendered as luminance-shaded ASCII, slowly tumbling. Old-school 3D rasterization for the terminal era.
