There is only so much you can do with a search page. But Google has worked wonders with theirs. From changing the Google logo to something topical through Google Doodles, to adding mini games for the London 2012 Olympics they definitely put as much fun into a simple search text box as possible.
Google's current design
After successfully redesigning the results page for tablets last year, mobile phones received the update just a few weeks ago. Now the desktop is set to get the same treatment, with the updated design hitting US browsers first, with other languages and regions following as soon as possible.
Google's tweaked results page
As you can see, the new design moves the navigation menu on the left into tab like buttons below the search term, above the results. The top black navigation bar has also gone.
Google is changing the design to focus on the answers you’re looking for, whether from web results or the Knowledge Graph feature. The same tools are all still available; you just need to click on ‘Search Tools’ to access them.
