North American productivity has ground to a halt today, thanks to the first-ever "playable doodle" on Google's homepage. To honor Pac-Man's 30th anniversary, Google has created an in-browser version of the arcade classic. Clicking "Insert Coin" starts a one-player game; clicking it twice adds Ms. Pac-Man (controlled with A, W, S and D) for a local multiplayer game. Google developer Marcin Wichary says despite the customized gameboard, this version is lovingly accurate: "Google doodler Ryan Germick and I made sure to include Pac-Man's original game logic, graphics and sounds, bring back ghosts' individual personalities, and even recreate original bugs from this 1980s masterpiece." The game will be active for 48 hours, so until Sunday morning. What game should Google feature next? I'm voting Elevator Action.
