Learn Free is a short documentary introducing unschooling. It gives a decent overview of most of the usual FAQs of unschooling in an accessible and well-tempered format. My little sister made it and we're in it, along with the folks over at Almost Always Hungry.
I can't believe I forgot to post my sister's documentary. I'm an idiot! She finally published it online in September. I forwarded it to every unschooling list I'm on but somehow never put it on my own dang site. Way to go.
