my latest favorite way to declare js classes...

js-class.js

//
  var Grid = new Function();

  Grid.initialize = function(){
    var args = Array.prototype.slice.apply(arguments);

    var grid = new Grid();

    grid.initialize.apply(grid, args);

    return grid;
  };


  Grid.prototype.initialize = function(){
    var args = Array.prototype.slice.apply(arguments);
    var grid = this;
    
    // initialize that bad boy...
  };

sure!
