Very cool. It works for me in chrome, but its shows this message four times before working In windowStack::windowStack() : The DOM element passed was invalid.

It doesn't work for me in Firefox 5, but I don't have flash on my ff. Do I need that? edit: more detail: On firefox, its sometimes a black screen, and sometimes a blue/green wavy screen.
