From here (link removed) you can download Google’s Pacman.
The current version has a couple problems. Sound don’t work when working offline. And when working online, for example on a local server, it won’t work on Opera but works fine in IE and Firefox.
Hour is getting late and I can’t really be bothered any longer with it, will eventually get back up to it. In the meanwhile, enjoy.
Update: Look here for an update.
