This script will allow you to add an easter egg to your website. When a user on your site enters the Konami Code:
Up, Up, Down, Down, Left, Right, Left, Right, B, A
A Contra character will scroll across the screen and an audio sample will play.
A basic example can be found in the 'example' directory. There is also a minimized version that is slightly smaller than the full expanded source.
Feel free to fork this, or use it in any project you wish.
$ bower install js-contra
