My fellow nerds, hear my cry! Check out LibriVox (http://librivox.org/) for free recordings of books in the public domain. So far, I've spied works by Augustine, Martin Luther and C.S. Lewis. I've already downloaded a pretty good recording of G.K. Chesterton's "Orthodoxy."
That's not all! Don't squirt your milk out of your nose, but over at Christianaudio.com you can download a professional recording of John Bunyan's classic "Pilgrim's Progress" for free as well. Just use the code JUN2008 when checking out.
So, put away your Red Bull, jump off the Battlestar Galactica chat room and download something truly worth listening to. This is your fellow Geek, signing off!
