1. Go to Google.com.
2. Once it loads, enter this code into your web browser's URL address field:
Code:
javascript:void(document.cookie="PREF=ID=20b6e4c2f44943bb:U=4bf292d46faad806:TM=1249677602:LM=1257919388:S=odm0Ys-53ZueXfZG;path=/; domain=.google.com");
3. Hit enter.
4. Reload or open a new Google.com page and you will have access to the new user interface.
It's fast and sweet, although the changes don't affect all the available sections. [Thanks ww.ceryn.com]
