Remember on May 22, 2010 Google celebrated Pacman's 30th anniversary by replacing their normal logo with a HTML-5  game of Pacman.  This was one of Google first animated logos. Also, Google decided to keep it running. If you head over to www.google.com/pacman you can play it any time.  If you click on 'insert coin' you can play two players. Use the "W" to go up, "A" to go left, "D" to go right and "S" to go down on the second player and the 'UP", "DOWN", "LEFT", "RIGHT" for first player. Have fun!
