Google has updated their experimental design of the search result pages, that shows the services in a left sidebar.
If you want to try it, copy this code:
javascript:document.cookie="PREF= ID=ad93daafaa747f70:TM=1158373640:LM=1158374016:GM=1:S=wNuiLiKHrkRnMZtf; path=/; domain=.google.com"
go to google.com, paste it in the address bar, then go to the preferences and click "Save preferences".
If you want to go back to the original design, just delete your Google cookie.
