Google- this space intentionally left blank?

Before:

Few seconds later:

I wonder what is Google up to now.. See the before and after google site..

Why did they put it blank intentionally?

So here’s why:

“At Google, we run anywhere from 50 to 200 experiments at any given time on Google sites around the world. Today, we’re testing several homepage design changes. This is just a test, and a way for us to gauge whether our users will like an even simpler search interface,” Google commented on the tests.” (Source: http://news.softpedia.com/news/Google-Extends-the-Fading-Homepage-Tests-125899.shtml)

If i had not stumbled into this news, i would think that it may be another innovation by Google again. Google never failed to impress me.
