Google "I am feeling ...." button on home page animates, makes you 'puzzled', 'hungry' and much more

We've been noticing an interesting thing on the Google Homepage. As soon as you hover your mouse cursor over the regular 'I'm feeling lucky' button, it animates and presents you with several options like "I'm feeling puzzled", "I'm feeling hungry", "I'm feeling trendy" and so on. Click on the button takes you to various Google Project pages or search terms. For example, we clicked on the 'I'm feeling hungry' button and it took me to search results for the keyword "restaurants". We don't know what's cooking in Google brains at the moment but we are keeping an eye on the update.



Google's been known to offer innovative logos (Google Doodles) depending on the events or occasions. But this is the first time we've noticed Google playing with the I'm feeling lucky button. It's quite innovative and interesting. Take a look at it ( I can only spot it on Google.com and not the regional search pages viz. google.co.in) and tell me what exactly is Google trying to 'promote'; Google after all makes all its money through advertisements, right?

Update: It turns out that we were late to notice this update. Google rolled this out on August 24, 2012.
