I have come to the realisation that the Doodles must be Geo-specific as looking through the Gallery there are sometimes 2 Doodles on the same day; and of the 161 so far this year an awful lot I haven't seen!
I'm a huge Google Doodle fan... a lot of them are fun, and bring a smile to your face when you're searching the net. They've been around since 1998 and there have been over 1,000!
