Just in case you follow a video tutorial, where they talk about “Tears of steel” or “Sintel” or “Big Buck Bunny” or “Yo Frankie” and you probably don’t know what that is: It’s a movie or a game done with and for Blender. From 2006 until 2012 it has been a strategy of the Blender Foundation to improve its software with the production of short movies: http://www.blender.org/features-gallery/blender-open-projects/.

experimental blender versions: http://graphicall.org/ Since Blender is open source, the main development happens in branches = different experimental blender versions, rather than plugins. There are python scripts of course to add on functionalities, but those are intended for the automation of the existing tools.
Freestyle:
One of these versions incorporates the freestyle modul, which is developed for non-fotorealistic rendering. Here you can find some basic config hints, how to use it (click on the image on the left).
