Google is now testing an experimental design on YouTube, called Cosmic Panda. The new design is not enabled by default, but you can use it today by enabling it in YouTube’s TestTube.
The design is totally new and focused on channels, playlists, and videos. Besides the obvious style change, other features include auto-refresh commenting, dark background on video pages, and much more. Give it a try yourself.

I like it, this whole streamlining the user interface over all googles services is great the only thing I would say is that It would be better if the background surrounding the video player was black rather then grey
