+(function( window ) {

nit: Any reason you pass in window as a parameter here to this anonymous
function? If you don't, I'm pretty sure references to window will just resolve
properly. 

Additionally, I think (but am not positive) that window is a read-only property
in JS that always refers to the global object and can't be overridden.

style nit: we use variableNamesLikeThis for JS code (this variable and other
names here too)
