LearnLiberty's videos are getting better and better. Along with Madsen's excellent Economics is Fun series, they provide neat, entertaining, informative and, best of all, short takes on controversial economic and philosophical issues. 

The video above is a superb example: visually interesting as well as educational. I can only hope that videos like these make it beyond libertarian circles to real wavers, because they're such quality that they deserve a wide audience. No doubt they can help to change some minds, too.
