Thank goodness Google’s working on the really important stuff, like adding sound effects to SearchWiki, instead of releasing the promised off button to that dreaded service.

Although, I have to admit it’s pretty cool. To add the sound effect, turn this Google experiment on and delete a search result in Google search (you have to have SearchWiki turned on). It makes a Desktop Tower Defense like sound, recorded by co-founder Sergey Brin himself. Check it out in the video below.

Of course I’m now deleting search results like crazy to make the sound, which has wrecked my search results. I guess today’s a writeoff for SearchWiki data collection procedure.
