Google has been learnt to be testing a new version of its home page on certain testers. The new design improves upon the logo, web page aesthetics like border colors and link underline, improves upon the sidebar display,etc.
For instance, the main search result link is the only text on the page to be underlined. Other links that point to Cache, Similar links,etc. are no longer underlined. Also, the sidebar now includes small icons for categories like Images, Blogs, Maps,etc.
Here are some screenshots from the new web design
