This Week's Recommendations: The Tailenders, by the filmmaker Adele Horne, gets into the nuts and bolts of far-flung proselytizing with hand-crank technology. ...I thought of the Global Recordings Network, an evangelical organization in Los Angeles with 70 years of experience introducing technology to underserved populations. In the process of recording Bible stories in every known language, Global Recordings has created a variety of hand-cranked machines, which it delivers to remote places, where Christian parables can be played without a power source. In The Tailenders,a 2005 documentary about the organization, the alien-looking contraptions can be seen making converts. But not necessarily to Christianity. Rather, people who hear the recordings come to desire, somehow, simply to share in the supernaturalism of disembodied audio. Whoever controls these animistic effects, it seems, must be worth listening to. When missionaries approach, these people are vulnerable, having just witnessed a small miracle.
