Come and participate in the test of Google's experimental search right now.

If you like Google's Experimental Search released in May, you can now choose one as your default Google search. Go directly to the Google Experimental Search page located in the Google Labs, select one of the four options, and when you return to the Google homepage, you'll find that the selected experimental search has become the default. You can only select one experimental search at a time, but you can change, disable it, or send feedback at any time via the drop-down menu next to "Experiment" in the upper right corner of the page.
