Techo-Net discovered yet a new Google user interface, this one is with the Google black bar at the top of the pages.
So how do you remove it? Right now if you go to Google via http://www.google.com/?esrch=Agad::Public, notice the ?esrch=Agad::Public part, it will turn off the black bar and maybe some other features.
Here is a picture with the black bar on and off:
A bit refreshing, don't you think?
