EmergentSim, a Browser-Based Particle Laboratory
A local browser tool for building particle simulations, defining ball types and force interactions, and rendering the result as a preview or video.
Why it surfaced
EmergentSim exposes the machinery rather than hiding it: users can place objects singly, in grids, lines, or rings; tune physics, damping, walls, and frame rate; then define JSON-backed ball types and pairwise force segments. It is an unusually concrete little laboratory for experimenting with simulated worlds.
