Google have achieved a brand new look. As well they added voice search. What is voice search? Click the tiny Microphone next to the search box , then say what you wan't to search , and see the magic happen. It will actually search for what you said.
That little screenshot will help you find it :D Google also changed their look and feel , theme , and the way the instant search works. Unfortunately all these works only on "Google Chrome" "Firefox" "IE8" and "Saffari" and maybe "Opera"
Have fun exploring Google's new features. And we all love google , don't we? :)
