I've been putting a podcast together with a friend of mine to highlight the wealth (and dearth) of public domain stories out there. We cover a story, it's contents and characters, then put together several new spins that can be used to take it into new realms. Since it's all public domain, we're basically offering these ideas up for whoever wants them.
Our first three offerings are Don Quixote, Anne of Green Gables, and A Christmas Carol, with fantasy, scifi, & horror twists and more for all three!
