We need to implement the animation of intro launch. However I'm not sure if this animation contains performance / implementation difficulty. We may need some discussion before implementing. See link below . : https://docs.google.com/a/mozilla.com/file/d/0B2-G3kew1WpXVUxfZ2VlZVBMbUU/edit
Comment from Scott: 1.Circle expand into black. 2.Fade in from black to just clock and background. 3.At the same time, The four widgets start sliding in, with "fly-in" bezier, with length of 1 second.
fly-in bezier: cubic-bezier (0.0, 0.0 , 0.0, 1.0)

Comment on attachment 8616537 [details] [review] Patch This part looks good to me. The animation should have zoom-in animation of background and zoom-out animation of clock. Please file another bug to implement them. Thanks.
