Here is a great book I discovered on the Lessig blog.
“You probably use Google everyday, but do you know… the Google Snake Game? Googledromes? Memecodes? Googlesport? The Google Calculator? Googlepark and Google Weddings? Google hacking, fighting and rhyming? In this book, you’ll find Google-related games, cartoons, oddities, tips, stories and everything else that’s fun. Reading it, you won’t be the same searcher as before! (From the author of Google Blogoscoped.)”
