Google doodle on Google.co.in, Anant Pai's birthday. (google.co.in)

The odd thing is, I see this when I hit 'change to google.com' as well, although, some friends of mine in the US still see the Albert Szent-Györgyi doodle (even when they hit 'change to google.com'). Has Google started an IP based content system? As in not for the search results, but for the actual home page itself? I did not notice this before.
