Google has launched a new experimental version of their recently introduced SearchWiki interface which helps better target results. This latest Google Labs experiment introduces sound effects that make removing results from SERPs fun! When users participating in the experiment take aim at the "X" icon which removes results and and then click, they'll hear target practice like sound in addition to the SearchWiki animation. According to Google, the new sound effect was recorded by Co-Founder and President, Technology, Sergey Brin.
