Interactive simulations that run entirely in your browser. Each one is a small, dependency-free implementation of a model I find worth playing with — the point is to expose the parameters and let you push the system around, rather than to show a finished figure.
Source for all of them lives under static/sims/ in the
site repository.
An n×n grid of chaotic double pendulums, spring-coupled to their neighbours on a torus. One slider takes the system from independent chaos to global synchronization — watched live on a phase heatmap.
From a maze to the Müller–Brown surface with one cost function: Dijkstra and A* hunting the lowest route between two minima, with temperature deciding what ’lowest’ means.
A few hundred lines of physics: N particles, K species, one asymmetric interaction matrix. Break Newton’s third law and the system starts building things.
