Anyone who visited Google last weekend may have noticed that the Google Doodle was a working game of Pac-Man. This was to celebrate the 30th Anniversary of Pac-Man and was only supposed to be up for 48 hours. It has proven to be so popular it has been given a new home at http://www.google.com/pacman/ and is here to stay.
Not only is the game insanely fun and an amazing recreation of the original game, it is also a great technical feat. Something like this is usually created using Flash, this game however is coded using HTML 5, the language that Apple is pushing for. I see great things ahead for HTML 5.
Go play the game and have fun.
