Interactive simulations of systems where complex, surprising behavior arises from simple local rules.
A flock of starlings wheels through the sky in perfect coordination, yet no bird is in charge. A traffic jam ripples backward through cars, though every driver just wants to move forward. Stripes form on a zebrafish from two chemicals that can only diffuse and react.
These explorations let you tune the rules and watch complexity emerge. Each simulation runs live in your browser. Adjust parameters, poke the system, and see what happens.
Five recurring ideas color-coded across the series. Watch for them, every simulation is a different arrangement of the same handful of pieces.
