Let’s face it…The Doctor Who theme song is boss. You can try to say otherwise, but you’d be wrong (and the Daleks might hunt you down for your inferior theme song appreciation). 
All the whirring, and then the epic ooo–ee-ooohs. So simple, yet it says so much. There have been countless tributes to it from a video that showcases the theme through the ages & another that covers it with a didgeridoo and a cello. But perhaps the coolest tribute to the theme song is Radiophonatron.
Radiophonatron is a BBC site that created buttons out of different sounds that went into the Classic Doctor Who themes. With a simple roll-over these buttons, you can create your own Whovian tune.

At long last, 
One nuance is the use of ‘Circles’ –a simple way of grouping friends and contacts through Gmail and Google Contacts.
Another distinct feature of Google+, ‘Sparks,’ is similar to the recently offered Bing-Facebook integration. ‘Sparks’ is a search engine field that will generate findings based upon the user’s interests, such as blogs, news, videos, etc. The user can then click on the relevant found item, add it to their interest list, and friends within the user’s Circle are able to see what others are liking.
Just as Facebook contracted a relationship with Skype to optimize video chat to Facebook users, coincidentally, Google+ offers ‘Hangout’ -think of a 10-person capacity chat room with video chat enabled. The idea is to have a virtual social mixer, where people can hold open-to-exclusive conversations with one another. Hangout also allows for anyone to share content, like a YouTube video and watch the video within the coterie.
