I'm an independent engine and systems developer building Particle Realms: one browser-native foundation for games, creation tools, simulation, and AI. Not a different engine for every idea.
I build the tools I wish existed—and the worlds to test them in.

Rendering, physics, audio, networking, and creation tools share the same foundation. Navi is the operator-facing assistant.

Native browser APIs at the core; no Node.js client runtime. Python supports tooling and testing. CPU/GPU parity is a design and validation goal, not a blanket claim about every subsystem.
Soul research explores persistent software individuals learning through language, perception, interaction, and shared experience inside 2D and 3D worlds.
Shared knowledge. Individual identities, memories, and points of view.
The Soul experiment: worlds, language, and generations
The target is about 100 Souls in a 2D world and 100 in a 3D world: populations you can observe as they learn, communicate, form relationships and families, and pass knowledge between generations.
A shared dictionary and learning system provide common ground. Each Soul keeps its own context, personality, goals, and memories rather than becoming a copy of everyone else. Language should be grounded in what an agent can perceive, who it is talking to, and what they are doing together.
This is research in progress, not a claim of finished artificial life or general intelligence. The goal is measurable learning and persistent training checkpoints—not a scripted simulation presented as a trained model.
Also on the workbench
Realm Forge + RealmScript — integrated creation tools and language/runtime research.
Physical worlds — particles, fluids, procedural materials, mechanical systems, and digital-twin experiments.
Connected worlds — peer discovery, synchronization, and shared spaces. The optional master server provides discovery and signaling, not gameplay authority.
Creative tools — experiments in music, modeling, books, and making things inside the platform.
These areas are at different stages. The engine documentation and individual releases are the reference for available capabilities.
Build the foundation. Let people build the worlds.
