For the 30th anniversary of Pac-Man, Google did a little funny and actually incorporated Pac-Man into their search engine for a short period of time in collaboration with Namco. And it's a cutesy little thing that they did that just kinda remembers everyone why Doodles even exist and what their purpose in anything even means. Although, Pac-Man "professionals" such as myself can attest that the product placement-map sucks compared to the perfectly puzzled together original, too many parts to get stuck in and many long hallways where you can get trapped by the ghosts in both ways.

So it kinda rocks, and it kinda doesn't at the same time.
