Display formatted examples of CSS styles from web project

We have a large web application (happens to be Meteor) with a large number of stylesheets across multiple directories. Is there a utility that will go through all of the stylesheets and create formatted output displaying examples of all of the styles. This might not be practical for all style types, as they need to work together. I envision this to by a way to be able to visually see all of the different options that are already available (for example all of the text formatting).

This seems like it would be very useful so that existing styles can be used for consistency, rather than having to continue to create new ones.

If such a utility doesn't exist... it'd be a kind of cool project for someone!

Thanks
