Proto-Synth Grid Engine: Building a Math-First 2D World Runtime That Feels 3D

I’m building Proto-Synth Grid Engine , also described in the repo as I/O Synth Grid Engine .

The project is an experimental, deterministic, low-weight world runtime where geometry is not just decoration. Geometry becomes structure, storage, routing, and execution space.

The core idea is:

Geometry = storage Movement = computation Entities = executors

Enter fullscreen mode

Exit fullscreen mode

Instead of building a heavy 3D stack first, the engine starts with deterministic 2D simulation logic and projects it into a visually 3D synth-grid interface.

What this is

Proto-Synth Grid Engine is a math-first simulation surface.

It treats the world like a programmable environment:

shell geometry defines the world

module blueprints attach systems into that shell

entities move through the grid as executors

grid mutations become event-shaped state changes

deterministic replay becomes possible through event logs and receipts
