Being gamers, I think it's pretty safe to assume we are all fans of Pac-Man. So, how would you like to play Pac-Man for the rest of your life? World's Biggest Pac-Man, which currently features 4,988 user-created mazes, gives you that opportunity. Just look at the amazing Bitmob level I created! 

I hope that you're as impressed with it as I am. I think this makes me an official game designer or something, but go ahead and try to make your own level. Just know that it won't be as good as mine.

Thanks to Robert Johnson for the find!
