Click flag to see lizard tiling. Then the lizards play a collective rock paper scissors. (Hold shift key then click flag for turbo mode). Each color is predator to one other color, as in the Common Side-Blotched Lizard, which come in three varieties (named after the color of their throats). Orange throats beat blue throats. Yellow throats beat orange throats. Blue throats beat yellow throats. Thus the three varieties play a kind of rock-paper-scissors game. Here, each color is vulnerable if next to two or more predators. The lizard shapes are like M.C.Escher's reptile tessellations.
The program fits the lizards together like a jigsaw puzzle. Then carries a series of invasions, like a collective rock-paper-scissors. Each color is vulnerable to invasion if next to two or more predators. See our board game version of this dynamic: https://lifepatternsemerging.com/little-tip There you will also find simulations of this game in NetLogo, using a square tiling instead of a hexagonal tiling. Also see our Scratch versions of this game using square tilings.
