This weekend saw the global Coderetreat happen, where developers all around the world worked in regional groups to improve their coding techniques, and to try out new ideas/languages.

In Manchester, our sessions revolved around Conway’s Game of Life, a simple cellular automaton. Working in pairs, every 45 minutes we would throw away our work and start again in a new pair.

Nothing is more frustrating than spending a whole day writing code, and having nothing to show for it. So this evening I hacked out a javascript implementation of life, and a HTML/JS front end for it. Set a grid size, then click on the cells to set the initial state. Start and stop the game and alter the state at any time.

You can try it out here, and the code is available to do with as you please on GitHub.
