Brilliant. Google have a 30th anniversary 'Doodle' of Pac-man and it's playable! Story HERE (in Spanish) and not sure if it is available in the US/UK version...of course I'm not sure how long it will last! Screengrab (note "Insert Coin"). With any luck you can play it HERE.
Update: I knew it couldn't possibly NOT be in English too: on CNET News "Google gets Pac-Man fever" and they even have a handy video game (beware soundtrack could become addictive). And on The Inquisitr, "Quit playing Google Pac Man and get back to work, everyone!"
