Implementation of the Conway's game of life in Clojure

game-of-life

A Clojure implementation of the famous Conway's game of life.

It's implemented in 60 x 60 matrix and displays in multicolor using Quil.

How to run it locally

lein run

How to require the cellular automaton framework

(require '[zone.lambda.game.board :as b :refer [DEAD ALIVE]])

Result

rules of the game

(defn neighbour-cells [block]
  (concat (subvec (vec block) 0 4) (subvec (vec  block) 5 9)))

  (count (filter #(= % ALIVE) (neighbour-cells block))))
(defn is-alive? [board i]

if you want to modify the colour

modify the code and re-run lein run

if you want to modify the initial state

modify the code and re-run lein run

if you want to modify the rules

modify the code and re-run lein run

or use Klipse for an interactive session :)
