Friday, I turned on the computer to discover Google's best doodle ever - an interactive Pac-Man 30th Anniversary commemorative doodle. Google's front page often has special artwork related to particular days of note - great artists' birthdays, dates of historic interest, current events. But I've never seen one that was actually interactive beyond the simple click-through to information ABOUT the doodle and related event(s).
The mere fact that the doodle is a WORKING video game is cool enough, but click the "insert coin" button twice in quick succession and you get a head-to-head, Pac-Man plus Ms. Pac-Man, team board. The W, S, A, and D keys control Ms. Pac-man while the arrows control the original dot-munching yellow ball.
I found this screen shot, but couldn't figure out how to make the interactive Pac-man work here. So, check out the official Google site (where sound is also included) while it's still online this weekend. If you miss it, this site may carry it indefinitely.
