It's just the Google homepage tribute to Pacman turning 30 today. A playable game starts up automatically, use the arrow keys to move Pacman. It's fun! You can get Ms Pacman to appear in that game by clicking the "insert coin" button twice and using the WASD keys to move :)

You can also just change your homepage to something other than google until tomorrow.

Thanks for your response. Now I know where the Pacman music is coming from. However, my homepage is Instapundit.com not Google. Also, the Pacman music keeps playing no matter what website I go to using Firefox. I'm curious if anyone else is experiencing the same thing.

I've been told about it, where do I find it????
