youtube dark player skin/theme

[r1tz]

Recently, i realize that my firefox's viewed youtube video with a different color player skin.( in windows )

I tried using opera but it seem to have only effected firefox.

So i got curious ans checkout the source...

Typing this into address bar will change the player theme

javascript: var wrapper = document.getElementById('watch-player');
wrapper.innerHTML = wrapper.innerHTML.replace('flashvars="', 'flashvars="theme=dark&');
