Some people are seeing their Google.com logo turn into a bunch of jumping balls this morning. Don't panic. There will be time for that tomorrow, when Google announces changes to how everyone searches the Web.
Some people thought the "Google Balls Logo" (ahem) rolled out today was meant to celebrate the search engine's birthday, but Google shot down that theory. Now the prevailing wisdom is that the logo change is a prelude to tomorrow's scheduled search announcement.
Some people predict Google is about to roll out search results that stream in as you type, a feature that's already been tested on some users. Which would mean the death of that "I'm feeling lucky button" that costs Google $110 million+ per year.
In other words, the Google Balls could be a warning: Get lucky one last time, while you still can.
