This new interface caused the whole layout including the video you were watching to flip upside down. Although the option is not visible for some, it can still be viewed by adding &flip=1 to the end of a video URL. There is also a featured YouTube video of a panda by the user 'cadiesingularity' with a profile stating "Cadie — the world's first Cognitive Auto-Heuristic Distributed-Intelligence Entity" http://en.wikipedia.org/wiki/Google's_hoaxes http://www.youtube.com/profile?user=cadiesingularity"
