AngularJS directive to cornify a web page when the "konami code" entered on the keyboard. I wrapped js I found on a blog into a DDO.

cornify.directive.js

ngApp.directive("cornify", function () {
  return {
    link: function (scope, element, attrs) {
      var konami_keys = [38, 38, 40, 40, 37, 39, 37, 39, 66, 65];
      var konami_index = 0;
      $(document).keydown(function(e){
          if (e.keyCode === konami_keys[konami_index++]) {
              if (konami_index === konami_keys.length) {
                  $(document).unbind('keydown', arguments.callee);
                  $.getScript('http://www.cornify.com/js/cornify.js',function(){
                      cornify_add();
                      $(document).keydown(cornify_add);
                  }); 
              }
          } else {
              konami_index = 0;
          }
      });
    }
  };
});

I have modified this directive a bit to take custom callback to call when user enters the konami code :) https://github.com/dos1/angular-konami/blob/master/angular-konami.js
