Those rapscallions at Google sure do seem to be having fun with the iPhone. Not only did they pull a fast one on Apple by using private API's to work their lift-the-phone-to-activate-voice-search magic, they snuck a little super-swipe activated easter egg in for the rest of us! Says the Google Mobile blog:

One evening in Zurich, after a late night cake run, we decided that our iPhone app, Google Mobile App with Voice Search, could do with a little bling. The result of this is a few extra options hidden below the preferences on the Settings tab. Trust us, they're down there... it just might take some perseverance to get to the bottom of things. Just keep trying!

Spoiler alert! Tap the cog icon to go to the settings screen, then swipe up over and over again to make the Bells and Whistles menu appear. From there, you can pick a new theme color, choose Chicken or Monkey as a sound, turn on a Live Waveform, and choose to Open Links in App.
