WHAT IS IT?

A simple cellular automata to generate Worley Noise(ish).

HOW IT WORKS

A handful of patches act as seeds. These are green, and marked "done" at setup. When you hit go, any patches who are NOT marked "done" ask if any of their neighbors are done. If any of their neighbors are done, they mark themselves done, and set their color based on tick count. This means that the further away a patch is from any of the seed patches, the higher the number of ticks will be before that patch can mark itself done, and therefore the brighter it will be.

HOW TO USE IT

Choose how many seeds/cells you want with the cell slider. Hit Setup to clear previous and generate seeds. Hit Go to run the model. It will stop when all cells are marked as done.

CREDITS AND REFERENCES
