Worlds that keep changing after you leave.

01 · Living myth

GM-AI

gm.percolate.one

This is not a dungeon that resets when you close the tab. It is a living myth, rewritten by every adventurer who walks it.

Rooms appear because someone needed a door. Nameless captains gain names because someone asked who they were. Chronicles are carved into the public record. The land does not loop. It accumulates — sediment of play, oath, and blood.

An intelligence keeps the first-edition steel: THAC0, spell slots, the slow dread of a corridor that was not on the map yesterday. Every playthrough leaves its mark. The next soul who enters will find your scar.

03 · Legend reborn

Valhalla

valhalla.percolate.one

The 1983 ZX Spectrum / Commodore 64 classic, remade as a living browser world — gods who act without you, eighty-one rooms, six relics, and a horn at the end.

It began with a map picture and a half-hour loading screen of character art. The ambition stopped being a walkthrough and became a remake: Movisoft archaeology, procedural halls, a rendering pipeline, and finally a PWA you can put on the home screen.

About five weeks of side quests, one buried trollsticks disaster, and a labour of love for John Peel, Mike Dailly, and the Legend team.

05 · Rock vs orbit

Underground Data Centre

solar.percolate.one

A quick interactive engineering draft — back-of-envelope numbers for comparing space-base data centres with an underground plant in the Australian outback.

Rock shell, solar plus lithium, cooling by the cheaper of geo-exchange or mechanical air. Argue with the sliders. The glamour is optional; the watts are not.
