Fast Flip is a horizontal scrolling tool that was recently added to Google News. This tool allows a user to scroll through visual thumbnails of source news websites and quick filter the options based on a set of predefined criteria such as "Most viewed," "recent," or top search interests such as "Glenn Beck" or "fishing."
The tool was designed to allow users to read the news stories online in the way they would in print--providing a related visual experience.
Fast Flip was introduced to the Google Labs back in September (2009) and appeared to be based on technology very similar to Searchme or Viewzi.
