Click the flag. Three colors of bird tiles are randomly distributed across a grid. Then the tiles exert peer pressure on neighbors to convert them to their color. But each color can convert only one other color, like Rock Paper Scissors (Red Rock, Purple Paper Green Scissors). A red tile neighboring three or more purple converts to red. A green neighboring three or more reds converts to red. A purple neighboring three or more greens converts to purple. Neighboring means "next to" including diagonals. That process repeats 50 times. Click spacebar to make it go for another 50 rounds.
Chris Keane of Flock Ecogames wrote this program based on our (Flock Ecogame's) board game "Little Tip." See our more complete simulation (in NetLogo) at lifepatternsemerging.com Each type has a predator and each type has a prey. This is like rock-paper-scissors except that prey is only vulnerable if neighboring three or more predators. By neighbors we mean "next to" including diagonals (so a tile could be next to up to eight of its predators). When you click on a tile the program counts its neighboring predators. If next to (neighboring) three or more predators, then it converts to its predator. We use our bird tiles in several other Scratch projects, and a NetLogo model. Chris Keane drew the bird tiles inspired by Escher's tiles.
