Google Mystery Logo 2 - Grey... With a Twist

Yesterday, Google's logo was a cryptic bouncing ball thingy. Today the home only has a grey (or some might say a "chrome") logo. Kind of a ho-hum logo after yesterday's boisterous display.

But when you start typing something in the search field...

it turns to color!

Here it is completed.

Like a double-rainbow all the way across the sky, it's got me asking, "What does this mean?"

Google may have some answers for us tomorrow though. We'll have to wait and see. It's clear this isn't just a birthday celebration, as I, along with the rest of the internet, previously thought.  

Some are speculating that Google's going to announce a new algorithm for indexing websites that uses the data collected through Google Analytics to help users find the most relevant sites for their search. If this is the case, then Yahoo and Bing might want to start emptying their desks. 

What's the Meaning Behind Google's Bouncing Balls Logo

As I've mentioned before, I love Google. Today's logo has me stumped though. Here's what it looks like when you load the page.

Then when you wait a second, the balls fall into place.

Plus, it's interactive! Run your mouse through them and the balls are repelled from the mouse!

I've been trying to figure out what it's all about, but I can't find anything. In the course of searching, I did, however, discover this interesting fact: 6 Nobel Laureates were born on September 6th and another Nobel Laureate died on September 6th. Weird huh?

If someone figures out what the logo is referring to, please let me know because I'm baffled.
