Zebra Stripes

Turing-pattern stripes self-organize out of pure noise.

Generative Art · a single painted seed plus one Phlux rule, simulated live · 96×96 grid

The rule that makes it move

This is the whole thing. Phluxel runs it on every cell, every step — the animation is what happens when you repeat it.

R = {SAT, R + ({AVG,(-1:1,-1:1).R} - {AVG,(-3:3,-3:3).R}) * 1.2}; G = {SAT, R * 0.62 + 18}; B = {SAT, 200 - R * 0.6}

Paste it into the Rule Editor, or pick Turing Stripes from the template list and skip the typing.

Make it yourself

1. Open Phluxel and start a new field, or click Zebra Stripes in the starter gallery to get this exact setup.
2. Turn Wrap edges on — this one is toroidal, so motion that leaves one side comes back on the other.
3. Press play. Change colours or numbers while it runs; you never have to stop and restart.
4. Export a seamless loop as GIF, APNG, MP4, a PNG sequence, or a sprite sheet.
