As the eerily familiar bleeps and bloops of video games past began eminating from my computer this morning, a friend nearby immediately recognized them and quipped that he'd spent "way too much time and brain cells playing that game". That game is Pac-Man and it's featured in a playable Google Doodle for the next 48 hours on the Google homepage. Sponsor The search engine is celebrating the video game legend's 30th birthday today (and tomorrow) with its first playable Google Doodle. To give it a shot, simply go to Google.com and press the "Insert Coin" button or wait a few seconds and the game will start up.
