Google background change (BP, automated changes, searches, etc.)

So, shortly before today (6/10), I tried to go to sleep, and left my computer. Google was the same blank white background it always is (I'm signed in usually for my e-mail, but haven't personalized my account).

A little restless, I wake up after the day changed to 6/10. Go to Google, and lo and behold, a brand new background is there. It looks like a close-up of the gulf, only (of course) the water is all clean and shiny, and looks like an inland area (or an old photo). Also, the Google logo is in all white, with a slight black outline on the letters.

So I search Google to see if there's something up, as they tend to personalize the homepage is there's an anniversary of something (Da Vinci's birthday, Pac Pan anniversary, etc.), but there's no search result.

I see a new link beneath the search that says, "Curious about today's homepage? Add your own background image now!". Thinking it would be the info I'm looking for - as neither the banner, nor the Google header is clickable for an explanation - I click on the link.

A window pops up, giving me a Search option and showing me thumbnails of personalized backgrounds I can choose from.

I search "BP Oil Spill", and it shows nothing, except for one anti-Obama sign and a few snapshots of the Gulf coast (sans oil). I search "Gulf Oil Spill" and the same criteria shows up.

So...

Is this part of BP's Google campaign to whitewash over the spill? To show an areal shot of a healthy, lush Gulf Coast, without being able to either change the background, except to something more neutral and pleasing?

It's just a weird thing to have happened suddenly, in such a short span of time. I must have been on Google only 20 minutes before the change of the day.
