-A tweet-sized, fork-to-play, community-curated collection of JavaScript.
-
-How to play
------------
-
-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!
-
-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.
-
-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.
-
-All entries must also be licensed under the [WTFPL](http://sam.zoy.org/wtfpl/) or equally permissive license.
-
-For more information
---------------------
-
-See the [140byt.es](http://140byt.es) site for a showcase of entries (built itself using 140-byte entries!), and follow [@140bytes](http://twitter.com/140bytes) on Twitter.
-
