....check it out...it's the soccer ball next to the resolution. Unfortunately it only works if you watch the video on the youtube site. You can now watch your favorite youtube video newly improved with the ethereal soothing new-age sound of the vuvuzela.
update: doesn't work on all videos....only seems to work on videos with under a million views published by a private party.... like this one here http://www.youtube.com/watch?v=poNNCj422bI&feature=related
