Popping that great American pastime into the site pulls up several small boxes showing off “baseball” through Google services such as Google Translate, Google Trends, Googel News and Google Earth, as well as links to create my own content through Gmail, Picasa and Moderator. There’s even a widget (of dubious utility) showing off a 3D image of a baseball.
