How do I simulate a bird flock?

Open this page and use the live Langton's Ant tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a bird flock from your own measurements.

Two rules: on white, turn right and flip the cell; on black, turn left and flip. After about 10,000 steps of apparent chaos, the ant spontaneously builds a periodic highway — order from simplicity.

s_{n + 1} = {turn right, c \to 1 turn left, c \to 0 c = 0 (white) c = 1 (black) n = 0

Reading this result: Early on the trail is small and near-symmetric — the same two rules run every step, so the outcome is fully deterministic no matter the speed.

About this simulation

The full Langton's Ant tool models a bird flock with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
