You all know my deal, so I’ll say it again: Bing! Hint: You can steer that background with the mouse or on-screen controls. Another interesting bit, this is done – as are all their animated backgrounds – through the use of the somewhat new HTML 5.0 specification, which among other things allows rich content such as videos, music, and other interactive content without requiring additional software be installed. In other words, if you click on a video link, it can play right in the browser without needing a separate piece of software installed such as MediaPlayer or Quicktime or VLC or whatever else instead. Also, notice the news story along the bottom in the screenshot about Microsoft releasing the source code of DOS and Word? Well guess what’s posted right below! See how it all comes together?
