    =========
    Game of Life - 140byt.es
    ========================

    A tweet-sized, fork-to-play, community-curated collection of JavaScript.
    An implementation of Conway's [Game of Life](http://en.wikipedia.org/wiki/Conway's_Game_of_Life) in less than 140 bytes of JavaScript.

    How to play
    -----------
    See the example: [ubilabs.net/projects/game-of-live](http://www.ubilabs.net/projects/game-of-live)

    1. Click the ![Fork](https://d3nwyuy0nl342s.cloudfront.net/images/gist/buttons/fork_button.png) button above to fork this gist.
    2. Modify all the files to according to the rules below.
    3. Save your entry and tweet it up!
    Usage
    -----

    Keep in mind that thanks to the awesome sensibilities of the GitHub team, gists are just repos. So feel free to clone yours and work locally for a more comfortable environment, and to allow commit messages.
    life (
    input, // input array
    size // size (width and height) of stage
    )

    // returns the modificated input string

    Rules
    -----
    All entries must exist in an `index.js` file, whose contents are

    1. an assignable, valid Javascript expression that
    2. contains no more than 140 bytes, and
    3. does not leak to the global scope.
    Author
    ------

    All entries must also be licensed under the [WTFPL](http://sam.zoy.org/wtfpl/) or equally permissive license.
