Not sure if this is an April Fool's joke or just something amazing that Google did, but you can now PLAY PAC-MAN IN GOOGLE MAPS. Seriously, just head here and hit the "Pac-Man" button in the bottom left corner.
It's all sorts of awesome. Try finding some wildly cool places and cities around the world to fight off some ghosts in. Here's downtown Paris by the Eiffel Tower, for example.
No word on how long this will stay up, so get a few rounds in before Google pulls it.
