The gates are open: a Marathon fan project in three days
On 2 June 2026 I started an empty repository at 11:24. By 14:08 the same afternoon, it held a working 3D explorer for the maps of Bungie's Marathon. By 08:38 on 4 June it had a squad simulation, adaptive rendering, a soundtrack and a design language borrowed from the game. It's live at marathon.withseismic.com.
It's a fan project. Nobody paid for it and nobody asked for it, but it's the clearest example I have of how my work has changed. The technical side was never the hard part. The hours were, and for years they decided what got cut before I'd written a line. This time nothing got cut, so taste led the project instead of the time I had.
Living mockups
Editable 3D product mockups with live screens and LED walls
Design & engineering · Built the scenes, surface mappings and inline editor
View Living mockups project- A set of Three.js product scenes — a newspaper, a phone in hand, a reflection room and an industrial laptop — where every screen, page and LED surface is a live, editable texture rather than a flat render.
- The headline and the artwork are edited inline; the change lands on the curved wall, the reflections and the phone display at once, because each surface is mapped back to one shared source.
- Backgrounds are generated, the reflection and emissive shaders are hand-written, and the whole set runs in the browser at interactive frame rates.
- Part of the Studies & Experiments gallery: a collection of standalone scenes that can be dragged, played and inspected.
Digital patterns
Generative poster system for an events programme
Design & engineering · Built the pattern engine, editor and export
View Digital patterns project- A story generator for a week of club nights: six animated pattern families — pixel, angular, wave and more — each seeded, coloured and typeset into a poster that stays legible at any scale.
- Every field on every poster is editable in place: date, genre, headline, colour, pattern scale and animation speed, with a one-click regenerate per poster.
- Posters export as stills for print and social, so the same system that runs on screen produces the programme's artwork.
Studies & Experiments
Interactive studies in 3D, shaders, sound and motion
Design & engineering · Built every scene, instrument and interaction
View Studies & Experiments project- A gallery of standalone scenes: a full event lighting show, editable living mockups, trading cards with prismatic foil, a working Roland 303 and 909 rack, a repair bench and a gravitational-lens shader.
- Each plate is its own build — Three.js scenes, custom GLSL, Web Audio, soft-body physics and print-style typography — and each responds to the pointer, keyboard or touch.
- The gallery itself is a piece of the work: a printed-sheet metaphor with registration marks, tape stock and a lens that pulls back while the sheet travels, plus a presentation mode that hides every instrument for demos and recordings.
